2nd March 1971

She did it again. She's been doing it more and more recently. It's as if she has completely forgotten that we used to get along. Ever since I got my letter on my eleventh birthday she's hated me. She thinks I'm different – maybe I am. I don't feel different though. I don't look different. Mummy and daddy say not to worry – she'll get used to it. But it really hurts when she does it. It's just so horrible. I don't understand how my sister can be so cruel. I thought she loved me. Sev thinks she's jealous. He says she just wants to be special like me too but I'm not so sure. She keeps doing it, calling me a freak. I'm not a freak am I? I hope not. I quite like who I am and I don't want to have to change.

I'm so excited. It's just so sad I can't talk to Petunia about it. We used to talk about everything. She was like my best friend, at least until I met Sev. She keeps saying it and it always makes me cry. She doesn't care. In fact I think she wants to make me cry. I don't think she likes me anymore. I think she might actually hate me. I didn't know it was possible to hate your sister. I guess that means she doesn't love me anymore.
