So, you've conveniently arranged a family get-together on the precise day I'm planning to visit her up in York, literally a week after I told you I was planning to do that. Well, it's not going to work. I don't know why you have such a ridiculous vendetta against my best friend, and this is where I'm putting my foot down. You've done a fine job of messing up my life and my mind; I'm not letting you destroy my closest friendship too. Being my mother is no excuse for what you've done- in fact, it should have stopped you.
Oh, and when I move into the house in September, I'm not coming back for the holidays. Ever. I'll actually prefer spending the weeks alone in a house than with you and the rest of the 'family'.
