Why Am I So Mean To My Crush And Other Boys?

Hmm. I think maybe it might have something to do with the fact that they (guys) and this one dude you speak of in particular, just don't know you well enough to understand or know that's just how you are. "To know me, you have to understand me. To understand me, you have to know me" is how I usually look at myself with females, or anyone at that, that don't know what makes me tick & wonder why I act the way I act, because I'm pretty weird (for lack of a better word) myself. So simple enough, I think the solution to your problem is to actually hang out with him outside of school. However in general with boys, I think its always best to give yourself opportunities to let people know what you're all about and vice versa. Just genuinely & casually get to know one another.

As far as how to not be mean to people? I'd say be more sympathetic and considerate of other people's feelings. You said yourself that you "laugh at other people when they get hurt". & although you don't find it funny, they see it as mean. Put yourself in their shoes and see how they feel ya know? Everything is funny when someone else get's hurt...until it actually happens to you and it's not so funny anymore lol. Lastly, understand the change you're looking for wont happen over night, so just be patient, work at it & in due time, you'll be just fine :-)

Don't speak to people
