Me and my sister both do gymnastics at a local gym. After on class i was bumped to the advanced class and my sister wouldn't talk to me for weeks.A couple days ago i had gotten some really bad rips and she was all like ''Wow I can't wait till I get my 1st rips'' and then i saw here swinging back and forth on the bar really hard and fast (i think the was trying to get rips, but she didnt get any so she hated my for it). Then she started working really hard and got put into the advanced class too. Then in class every day she hurts herself ( i mean falls from things and straining muscles Then waiting the class out for like 10 min the rising from the dead (tell the coach she will be fine and very dramatically joins the class) I think she is faking it. When ever i do good at a skill she gets hurts trying to do it the rolls her eyes at me. I think she is just trying to get attention. Then now my coach has spoken to me about team and my sister hates my guts. She is 13 and the throws temper tantrums before class and always has to try to do everything better than me ( But she really can't so she ends up getting hurt throwing her self into thing she is not ready for). I don't know what to do its really embarrassing. I can't really talk to my mom about it because when Cody does anything my mom acts like it never even happened. My mom tell me this is what little sisters do but come on really. I hardly want to go to gym with her because she is so hard to deal with. What do I do?
