She gets mad at me. Also I'm not allowed to be best friends with her friend. I thought we were a trio. I really thought I was included. Nope I just get to be there. She's planning on moving out soon. She's gonna be with her friends all the time. She cant wait to leave home. She has started getting very impatient with me. Like I struggle with things and she gets mad that she has to repeat herself. She's started telling me to shut up. I feel like I cant ever get it right. She acts all condescending and motherly too. She sets the rules when my mom isnt home. My sister is strict. She thinks she's more mature than I am.
