Actions speak louder than words and all of that, but the things you say definitely affect how other people see you and what they think of you.
You might think you’re just being “honest” or “keeping it real,” but certain habits in the way you talk can leave people with the impression that you’ve still got some serious growing up to do. It’s about more than just being polite; it’s about showing that you can handle the complexities of life without throwing your toys out of the pram the moment things don’t go your way.
There are certain phrases that, if they’re a regular part of your vocabulary, are bound to make everyone around you think that you’re a bit petulant. Whether you’re in the office or out with mates, the way you react to stress or disagreement tells a story about your maturity level. If you want to be taken seriously as an adult, here are the things you’ll probably want to stop saying to avoid being seen as a bit of a child.
1. “It’s not fair!”
This one is a classic, and it’s a one-way ticket to sounding like a whining kid in a supermarket. The reality is that life isn’t always fair, and pointing that out to everyone in earshot doesn’t actually change the situation or make people feel sorry for you. It just makes you look like you haven’t grasped how the world works yet. Instead of complaining about the unfairness of it all, try to focus on solutions or ways to improve things. Ask yourself what you can actually do to move the needle rather than just dwelling on the injustice.
2. “Whatever.”
Dismissing someone with a “whatever” is a bit of a low blow in any conversation. It comes across as apathetic, rude, and frankly, a bit lazy. It tells the other person that you’ve completely checked out and that you don’t value their opinion enough to even bother disagreeing with them. If you’re annoyed, or you don’t agree, it’s much more mature to actually express your thoughts or even just say you need five minutes to think about things. Shutting down the chat with a teenage eye-roll of a word is never the move.
3. “That’s not my job.”
Nothing makes you sound less like a team player than this phrase. Even if a task technically isn’t on your job description, flat-out refusing to help makes you seem narrow-minded and unwilling to pitch in when things get busy. Mature adults understand that sometimes you’ve got to muck in to get the job done. If you’re genuinely swamped and can’t take on anything else, it’s better to explain your current workload and ask for a bit of help prioritising your to-do list, rather than just washing your hands of the situation.
4. “I can’t adult today.”
We’ve all had those mornings where we’d rather stay under the duvet, but saying this out loud, even if you think it’s a bit of a laugh, suggests you’re struggling with basic responsibilities. It can make you seem unreliable or like you’re constantly one minor inconvenience away from a total meltdown. Instead of using a cutesy phrase to bin off your duties, try being specific about what’s actually wearing you down. It’s perfectly fine to admit you’re overwhelmed and need a breather, but do it in a way that shows you’re still in control.
5. “I’m bored!”
Constantly announcing that you’re bored makes you sound like a toddler who’s lost their favourite toy. As an adult, it’s generally expected that you can find ways to occupy yourself or take the initiative to change your situation. If you’re feeling understimulated at work or in your personal life, it’s on you to look for new challenges or hobbies. Shouting about your boredom just makes it seem like you’re waiting for someone else to come along and entertain you, which isn’t a great look.
6. “That’s not my problem.”
This is a pretty cold way to deal with the people around you, and it almost always comes across as selfish. While it’s true that you can’t solve every single issue that lands on your plate, showing a bit of empathy is a massive mark of maturity. Even if you can’t help directly, acknowledging the problem and offering a bit of support or a suggestion shows that you’re actually considerate of other people. Pushing it away as “not your problem” just makes you look like you only care about yourself.
7. “You’re just jealous.”
Accusing people of being jealous the second they criticise you or disagree with an idea is a very defensive, childish way to react. It suggests that you’re unable to handle any kind of feedback and that you’ve got a bit of an ego problem. Instead of assuming people are out to get you, try to actually listen to what they’re saying. Understanding another person’s perspective, even if it’s a bit tough to hear, shows that you’re open to growing and reflecting on your own actions.
8. “I’ll do it later.”
We’re all guilty of a bit of procrastination, but constantly putting things off makes you look irresponsible and a bit flaky. If you can’t get to something straight away, don’t just give a vague promise to do it “later”—give a specific time and actually stick to it. Following through on your word is one of the biggest signs of being a reliable adult. If you’re struggling to keep on top of things, it’s better to look into some better ways to manage your time rather than just letting the work pile up.
9. “It’s not my fault.”
Always deflecting blame makes you appear immature and unable to take proper responsibility for your actions. Even if a situation wasn’t entirely down to you, there’s almost always something you could’ve done differently or a way you could’ve helped fix the mess. Taking ownership of your part in a mistake instead of pointing fingers at everyone else shows a level of self-awareness that people actually respect. It’s much more adult to say, “I messed up, how do we fix it?” than to scramble for an excuse.
10. “I don’t care.”
Proclaiming that you don’t care, especially when it comes to important matters, makes you seem disengaged and a bit vacuous. It’s often used as a shield to look “cool” or detached, but it actually just makes you look like you lack the depth to form an opinion. If you truly don’t have a strong preference on something minor, try saying, “I’m happy either way” instead. If it’s a bigger issue, make the effort to understand why it matters to other people rather than just switching off.
11. “You always/You never…”
Using these massive generalisations in an argument is a classic playground tactic. It’s rarely ever true, and it’s a guaranteed way to make the other person get defensive and stop listening to you. It turns a specific problem into a character assassination, which never ends well. Instead of using sweeping statements, try to be specific about the exact behaviour that’s bothered you. Use concrete examples of what happened this time rather than trying to rewrite your entire history with that person.
12. “That’s stupid.”
Dismissing someone else’s ideas or opinions as “stupid” is not only rude, but it shows a real lack of critical thinking on your part. Even if you completely disagree with what’s being said, there are far more mature ways to express that. Hurling insults at an idea just makes you look like you’ve run out of actual arguments. Try asking questions to understand their logic better, or explain clearly why you see things differently. It shows you respect the person you’re talking to, even if you don’t respect the idea itself.
13. “I hate you.”
Throwing around words like “hate” in the heat of a moment is incredibly childish and can do long-term damage to your relationships. It’s a very teenage drama way of expressing anger that focuses on attacking the person rather than the problem. It’s perfectly okay to be fuming, but you’ve got to learn to express that frustration in a way that doesn’t burn bridges. Stick to “I” statements to explain how their actions have made you feel, rather than resorting to personal attacks that you’ll probably regret once you’ve calmed down.
14. “Leave me alone.”
While everyone needs a bit of peace and quiet sometimes, snapping and telling someone to leave you alone can come across as a bit bratty and dismissive. It’s the verbal equivalent of slamming your bedroom door. Instead of being blunt, try explaining that you just need a bit of time to yourself to decompress or that you’d prefer to talk about the issue later when you’re in a better headspace. It communicates exactly what you need without making the other person feel like they’ve done something wrong by just existing in your space.
15. “It’s not a big deal.”
Telling someone their concerns aren’t a big deal is a massive way to undermine them. Even if you don’t personally think something is important, it’s clearly a big deal to them, and dismissing it makes you seem insensitive and a bit out of touch. A more mature approach is to acknowledge their feelings, even if you don’t see the situation in the same light. You don’t have to agree with their reaction, but showing that you’ve heard them goes a long way in proving you’re the grown-up in the room.
16. “I’m not listening.”
Plugging your ears, whether you’re doing it literally or just mentally checking out, is the height of childish behaviour. Mature adults face uncomfortable conversations head-on, even when they’d rather be anywhere else. If a chat is becoming too much, or you’re starting to get too angry to be productive, it’s much better to say you need a break and promise to revisit the topic later. Shutting down completely just leaves the problem to fester and makes you look like you can’t handle reality.
17. “You can’t make me.”
This phrase practically screams rebellious teenager. As an adult, you should understand that life involves doing plenty of things you don’t necessarily want to do. Using this kind of defiant language makes you look like you’re fighting against an imaginary parent rather than dealing with a peer or a boss. If you have a legitimate reason for not wanting to do something, explain your perspective calmly and try to find a compromise. Digging your heels in for the sake of it just proves you’ve still got a lot of growing up to do.
