You honestly think this is fair, Jack? It happened nine months ago and it's not as clear cut as one might think it is. There were reasons for which I called you a cunt, but if those reasons were poor, I apologise. I always felt you made power the issue and I felt you wanted to teach me a lesson. Which you did say in those words.
But again, shutting off communication like this is also a power issue. If this is what you want to do, it is your right, but I don't think it's the right answer.
