I literally sleep like 2 hours a night If that and the one time I sleep more than that my sister decides to start a screaming match with my brother at 6 in the morning and then come in here screaming at me that I need to get up and deal with him.. Like don't start a big argument and then rely on me to fix it..leave me alone and let me sleep.
