In the years that I was living in shared accomodation with people & their pets, I encountered all manner of weird and lazy housemates.
Creepy, eccentric, entitled, idiotic, inconsiderate, jealous, lazy, petty tyrants, pervy, spoilt brats, thieving, noisy, nosy and unbelievably unhygenic.
Renting a room in a houseshare is a massive gamble on how odd or incompatible a few of the other housemates will be.
That's why I'll never go back to the days of living with another adult nor sharing a kitchen, bathroom or fridge.
