Contrary to popular belief, I don't hate you. And, in all actuality, I used to have respect for you.
I didn't ban Sirius because Remus told me not to. I didn't ban Draco because he explained himself.
You wanna know my problem with you? Fine.
You've been a bitch to me. It's happened more than once. You've talked about me behind my back, tried to get Remus on your side about things, and you've made some generally bitchy comments in my direction. It's happened before, and it'll happen again. *THAT'S* why I'm ignoring you. I figure if we don't talk, it won't happen.
What you did *was* self-centered and it *was* bitchy. How do you think Remus would act after something like this? He'd be catatonic. He'd have a mental break down. You didn't take his feelings into account. So yeah, I do have a right to call you self-centered and bitchy. Because this whole prank was self-centered and bitchy.
Banning or ignoring you won't resolve it, it's your punishment. Or, it was, until you were unbanned.
