Last roommate I had was a loudmouthed control freak who thought dishwashers were "for clean dishes only" and started confiscating kitchen supplies after I used them for arbitrary reasons, never talking to me about it, instead just leaving behind notes. Like, I used a dishtowel to clean some water that spilled on the counter. He got mad and confiscated it, for that. Like really? It's water. And if it's dirty, there's this new thing called "a washing machine," but I bet that dumbass thinks that's for clean clothes.
Perfectly good dishwasher, demanded we keep clean dishes in it. And that was just the tip of the iceberg. That, along with his douchebag attitude and a whole bunch of other bullshit like his loud voice eventually drove me out of that apartment to find a new one.
The one before that was a pot-smoking party animal.
So yeah . . . living alone is awesome. If I get a roommate, it'll be someone I know first or a significant other.
