Sister 

Noun//A sister is created by your parents therefore making them your sister. They can be one of two things 1. A best friend who you share everything with 2. A living nightmare that gets you into trouble and is gonna stick with you until you move out. Its usually the second option. If you have a sister...good luck. You’ll need it.

2. My sister broke the dining room window while practicing baseball, and she blamed it on me.
