Well it depends on who that person was. If it was someone your own age they probably don't like that your different and maybe because te don't like the same things as them. Being mature is always good. I am told different things, that i am really life smart (I doubt that) that i'm like a little kid, and that i'm quite mature in my ways. I don't know who i am but i guess i'm a mixture of both. I am the same age as you, but it depends on what your like. If te are like me and just don't like it when people act like four anno olds that fine. But there is a boy in my class and he is a bit too mature sometimes, like he wont let the class have a joke and if someone does a little thing he tells on them (that could also be counted as immature) I'm rambling here but basically i'm saying if your the type of person who pretends they know everything (which i doubt te are) and act like peoples parents then i would say te could probably loosen up a bit. If te are just into older stuff like different music, clothes (depending on what type) and different ideas of funny then te are fine. Okay my ramble is finished*Everyone cheers and pushes me off stage*
babina, I think that xXSweenyXx is trying to say that he's a bit annoyed with te not using capital letters where they belong. That's fine though. te type that way.
It depends on the type of people te hang out with. If te hang around kids who act like they're 10, you're probably in for some trouble as their immaturity will really annoy you. However if te hang around people who are as mature as te are then te should be fine.
Maturity is usually a good thing. It means you're responsible and likely don't go into random outbursts for the smallest inconvenient things. Or...something along that line. Besides, judging te right now (since I don't know you, its not going to be completely accurate), te seem slightly childish. te use a lot of exclamation points, laughs a bit, say "btw" instead of the entire thing, and apparently typed "think" instead of "thing". I wouldn't worry about not being fun o whatever te might associate maturity as bad.
