Mistress Infinity was so big on using things well and not wasting resources. She had just started living with her brother and she told him about her rules and he was on board. She lived with him for a while then she started to notice his habits of wasting things, and this pissed her off. She decided to confront him about it and he was not even sorry and she decided instead of cooking for two tonight, she was going to eat her share and then poop and feed him to make him learn a lesson
