Sorry this got so long winded, but I don't know how to explain the extent of the situation. I have never told this to anyone before. Sometimes, if I think about it too much like tonight, I feel responsible for all her problems. Like how she is much too insecure about herself, so defensive, and eager to please. She's 11 years old, and I suppose it should be one of those stages of growing up that everyone has, but I think it runs much deeper than that.
I am so, so mean to her.
Once, she spent close to a month carefully cutting up pieces of paper and fashioning them into her own 3-d pentominoes (she got the idea from a book she'd read) and in one moment of anger, I grabbed a hold of them and crushed them with my hands. She cried and threw whatever was left at me and I don't remember exactly, but I think I crushed those too. She never tried making them again.
And there are other moments like that. Tons of moments like that, actually. And now, when I yell, she cries and yells back and throws things and says she hates me and I'd never even realized it had gotten that far.
Tonight, she read one of the books she'd borrowed from the library out loud to me. I think we sat for an hour together, shoulders touching, laughing about this part and that part. It made me really sad afterward. She's my sister after all, no matter how fucked up everything is between us-- mainly because of me.
I'm leaving for college in a week and I feel like I want to make amends. I have been trying to be nicer all summer but I want to start over completely. I am so sorry and ashamed of myself and I really don't know how to get my point across to her.
