I have shoulder damage to my right shoulder now because of my brother. Thankfully he's stopped twisting my arm (I had my mom talk to him about it, but that didn't do anything, because my mom didn't really care. I had my dad talk to him, and he hasn't touched me since), and since I haven't been swimming in a few weeks, it doesn't hurt as much. I still can't brush my hair or teeth with my right hand now without my shoulder hurting, so I have to use my left hand, which makes me get toothpaste all over my mouth area. Not to mention that he calls me bad names (yes, they're the type of bad names that are bleeped out on TV) in virtually every sentence he directs at me.My advice is: If she says something nasty, leave the room. I know, you probably want to get back at her for saying something stupid and mean, but it usually doesn't help to say something back. Believe me, she probably likes it when you answer her, it makes her happy because then she can think how 'stupid' your answer was. And when you actually do offend her, she'll just get even more mad and might hurt you.
