If you like things tidy, living with other people is hard. You have to maneuver through their dirty clothes, go on a scavenger hunt every time you need a clean plate, and work part-time as a garbage collector. But if you’re unlucky enough, you might move in with an individual that’s impossible to live with. No matter if you’re high-maintenance or chill as a goldfish. The Internet calls these creatures ‘monsters’. And rightfully so. Who else could keep a potato in their cupboard so long that it starts sprouting? Or leave so much hair on the wall of a shower that you could make a wig out of it?
