Oddly enough, what bothered me most about those pages was her cutting the power! As someone who's lived in an apartment where the power randomly cuts off, I know how terribly inconvenient that is. There goes your alarm, the electric water heater shuts off in the middle of your shower, your dinner's ruined, etc etc. It's really disrespctful to everyone else, and shows her as being terribly self-absorbed.
Also I do hope it's not a building where tenants pay for their own electricity, cuz then her stealing power is even worse. She should just get a generator or a solar panel or something.
