why do I even bother sometimes

Just another day in my life. My sister obvioulsly thinks dishes will wash themselves. It is now Tuesday and the George Foreman grill is still sitting on the counter, covered in sesame ginger sauce, mushrooms, and steak parts. The sink is full of dishes and she made all of these dirty on Sunday afternoon. She doesn't have a job and she is on Spring Break from school, so there is no reason for them to still be dirty. I find it disgusting and repulsive. She thinks I am being mean to her because I locked the dead bolt last night...Didn't know if she was coming home last night, so I wasn't going to leave the door unlocked and it was already after 11:30pm. I really cannot wait until December comes...I will do anything to be out of here
