Do you know how some people are only quirky in a superficial sense? Like they have some hobbies that aren't prepackaged, but you get to know them and they're really following some kind of crowd anyways?

I don't know what I really mean by that, but if someone agrees "we should hang out" and then repeatedly forgets about what you suggested, that person probably doesn't care about you in particular, right? ...it's that "in particular" part that bugs me. Someone who says "G'night, I love you all" but never actually pays attention to people as individuals...
...it's too casual. She probably doesn't care, so I shouldn't care either. I think I was just trying to make something work that would never work, especially since her circle of friends is likely full.

I just don't like it when people say they'll accept you and then more-or-less ignore you unless you speak up, because there's so many other people to be heard over. I was friends with the most popular kid in high school, but he was in too many places to actually pay attention to the people he surrounded himself with. So I'm wary of people who follow the same pattern.
