My sister (annoying, Majorly!!!!)

My sister's name is Asha but I call her Stubby for some reason. She is 3 years old and she's REALLY annoying. She go's in my room and messes up my bed, she goes in my room and steals my stuff like my MP3, etc. Also while me and my friend are kicking a ball on the tramp she comes on and we don't want to kick the ball because she would probably cry and tell on us. Sometimes when I'm watching T.V. she comes in and pulls my hair and messes up the T.V. Soon, I'm gonna get a lock on my bedroom door. I sometimes annoy her but she usually starts it. I think she annoys me because she feels safe around me. She used to call me Rara when she was 1 and 2 but now she calls me Rohan. She's probably gonna get more annoying when she's older.
