I have a younger sister. She's 18 and I'm 21. I have never gotten along with her and people think I'm crazy when I describe our relationship. She's very selfish, thinks she's better than everyone and has no respect for anyone including my mom. Many say oh it's just a phase but this phase has been going on since she was a kid. She has no friends and can't keep a friend for more than 2 months. She has anger issues and likes to start fights with anyone. She refuses to listen to anyone and is really fake. She'll be nice to you but turn on you if you make her mad. Her twin brother, I and even my mom can't stand her at home. My mom can't even joke with her and she feels sorry for her because she's going to end up alone in life. My sister is pretty and has been offered modeling contracts but her personality is very ugly. Everywhere she works she has problems but because she's so sweet and manipulative she gets a lot of people fired. She lies a lot too and even got a teacher from her middle school fired. We have tried therapy for her but it didn't work. We never say hi or bye to each other and when she's home my brother and I just ignore her. She doesn't try to talk to us but she has a good job and likes to show off with all her shopping. She doesn't care for her dog so we've all taken care of her and she finds her so annoying she's thrown away her toys or hidden them. My sister doesn't stay home often, but when she does even our dog is wary of her. She's called the police on my brother when she hit him on the head with a bat when he didn't even touch her and he had to go to the hospital. She likes to be the victim all the time. My mom and I just can't wait for her to graduate and get out. I told my mom if I was going to be our main provider after I graduate too, I want her out.
