I've always considered myself incredibly mature, but after an argument with a friend, I was told to grow up and listen for once. I was really shocked by this, because I've never been told that by anyone before. I'm someone who is more of a gentleman than anything else and I find it really hard to criticize people unless they deserve it. I don't see how I need to grow up, and if I need to grow up, I don't know how to. I don't like to dismiss things, as whether right or wrong, so I'm not quite sure how to take this. While I usually don't ever take criticism to heart, I don't ignore it either. Since I don't ever talk about this sort of stuff to anyone, I thought it best to post it here. While obviously no one here knows me at all, I would still like to hear your opinion.
