Okay, okay, that's good, GOD DAMMIT. THAT WAS THE WHOLE REASON I CALLED YOU!
Monsters. They can strike any house, anywhere. Much like going to the doctor for a cold and learning out you have cancer, you often find out you've got them in the least expected ways. Even worse if you're this apartment owner, now the monster won't even be slowed down by the mold and it's getting much better ventilation from your bathroom. Which means it can smell when you're in there. Which means any time you use the toilet, you're at your most vulnerable. Pantsless, immobilized by your business, it can just sneak up on you and BAM! You've been monstered.
