Maturity isn’t a simple question, like I said in the forum about good and bad deeds; it depends on your view. You friends might think you are immature because you laugh at stupid, "childish" jokes. I got called immature because I watch yugioh, they think it’s immature, whereas I think the series is cool. It’s all up to what people think, there isn’t an overall childishness that can describe people. Like I say that my brother is a child because he is 19 but he still buys figurines because he thinks they look cool, I don’t exactly mean that he is childish, I am only referring to the fact that he should have gotten over it by now, but he hasn’t because its one of the things he likes, and when you accept that, you don’t see maturity you just see what a person is like.
