define what a bad room mate is... 1. occupies the bathroom for more than an hour every day. including brushing her teeth for about 30 minutes. (which I never figure out how can one brushes teeth for that long!)
2. simply throws all her dirty clothes into the laundry basket but never wash them, hang them, or collect them. she just waits for the clothes to turn into clean ones again and show up on her bed automatically.
