Icefire: That's what happened to me. She stopped speaking to me one day. I'm lucky if she acknowledges my existance before she bumps into me.
The damnable thing is that no one, no one, knows why. She won't say. If someone tries to bring it up in conversation she pretends not to hear them. She won't tell her brother, her friends, her parents, anyone. It's a question I've thought over many times, seeking some offense, some insult, I offered, and I just draw a blank. So I've been sitting here in the dark for years without a clue what went wrong, no sense of closure.
It would be easier if I could hate her for inflicting the kind of pain she did. But I don't know if it was my fault somehow.
