Problems at home??????????

Ok well it all started when my sister took the car at 1200am at night no license and she got pulled over for racing, then my mom and stepdad were very mad. My mom got really mad, but my stepdad in my opinion looked at it as a way to f**ck with my sister. So the next day he woke her up at 11am and forced her to go outside an pull weeds for 2 hours then after that we went out to eat and he continuesly called her names like stupid,clueless,ect. Then he mocked her stupidity all day long when we went to barnes and noble he said everyone can get a book because she's a felon even though she isn't. Then when he left he mocked her to open her arms to make sure she didn't steal anything when he knows she would nvr do that then we went home and 2 more hours of weeds, then he made her read books to my little sister, after she was done she wanted to lay down but my stepdad made here do here homework that's required to use a computor which he confied then at night she made cupcakes for us and my stepdad came and said "get the f**k out of here I don't want to see your face " then that's wen my mom said HEY! Don't talk to her like that then my stepdad said a lot of bad stuff about why she should be talked to tlike that then he threw a globe and knocked my little sister then they said they would get a divorce what's ur opinion on this??
