Yeah, I have. Well, sortof.
My friend is better friends with this other girl in our group, who hates my guts for some utterly inane reason (one that she won't tell me. I think it's because I was flirting with her boyfriend, and at the time I didn't even know I was doing it -- besides, he was flirting back), and the girl that hates me turned everyone else against me.
I'm kind of not a nice person at all, so she got everyone to ostracize me. I ended up confronting them about this, and the first girl, one of my best friends, says "I'm tired of you bagging on everyone. I just can't hang out with you anymore. I'm not trying to kick you out of the group or anything, but we can't be friends."
I've only ever bagged on that other girl, who is just a heinous creature. And she couldn't kick me out of the group if she tried.
The next day, we start talking about the previous day and she tells me "No, I never said I didn't want to be your friend." Well, ya sure made it awfully clear.
I guess the moral of this story is that I hate high school. Also I can't stay on topic when posting.
