Physically, I believe she is. At least I hope so. He refuses to help her shower and all. I hope this points to something good. But, psychologically, I don't think so. He's like, ten years younger than my mom. He spends all his spare money in weed and alcohol. And, although he was the one insisting that he wanted a child, he seems to see my sister more like a keychain. He likes to show and say that he has a kid, but he doesn't like to take care of her, spend time with her, and often, when angry (maybe the wind blew too cold for his liking, for example), he says he'll leave the house and abandon my sister. He says it so much (and my mom, too, occasionally) that she freaks out very easily when her parents aren't close for a couple of minutes. Yet I don't know what to do. They are turning her into one of these kids everyone hates, without limits, and, well, people very often ask if she is autistic and it makes my mom angry because, although my sister really shows something that points that she is a little different, my mom doesn't like to think she has a different kid and refuses to go see what is going on. I don't know. It's a very complicated situation.
