You were deciding if you should be friends. That's the exact behaviour you describe. You see friendship is natural and just develops. It's not a decision process in any way. You like people or you don't. End of story.
Its normally because of parents spoiling them or they dont care. Or they moved a lot or never actually had a stable home. <br />
Just ingore them. They're normally up to no good. <br />
I was friends with quite a bit of them.
My personality allows me to get along with anyone. They weren't really my friends. Like I wouldn't of done everything they did. They pretty much came to me because I'm pretty good at solving problems and drama. And they knew not to be mean to me or around me because they know I don't allow bullying around me.
Believe me, it's not just teens.
