Input: I'm not talking about sharing food or objects, I've got no problem with that. But for some reason I feel really bothered and uncomfortable when I have to share "traits of personality" with them. This goes both to stuff like bands we have in common, or with more serious stuff like telling them about my personal life, what I feel, why I'm upset, etc.

First, I just don't really enjoy talking about movies, music and books I like, much less with someone that's enthusiastic about it. I like to feel that they're just mine, so talking about it kinda takes away the 'magic'. I just like to enjoy my stuff in silence.

Second, growing up, my parents taught me lots of times not to 'overshare' because sometimes we don't know if we can really trust someone, and honestly, I think that's a good thing. Probably saved me more than I think. But there's been some times where I'm upset at my friends or something else, and when they asked me I'd just be distant and not tell them. 

They've told multiple times that I'm too closed and that it would make our friendship a lot better, but I don't want to. So, AITA for not wanting to share with others?
