what's your problem

My sis's exams are over and she being a total ass. Spends 80% of her time at home in my room facing the stupid computer watching youtube. It's my room and i'm having exams soon. Shouldn't she follow my schedule instead and use the computer when i'm not at home? Thanks to my lousy and unstable wireless internet. Most of the time it only works on the wired unit, thus the internet cable has to be shared between 2 computers, which also makes her room's computer useless as the wireless connection sux. Maybe i should start studying in school where i can tap on the MEGA internet, or camp at nithe's house after he shifts so that i can save my ears from "What's your problem".
