I had a housemate coupled called Colin and Natasha. They were rarely seen apart so we referred to them as "Nolin". I would do a literal 14 hour shift and not hear/see a thing, and then he would randomly come downstairs. Think he was nocturnal.Housemate has been away emergency catsitting for about 10 days now. She's popped home quietly to grab stuff once or twice but otherwise partner and I have been left alone. I've been doing DIY, clearing the kitchen, deep cleaned and descaled both bathrooms as there's no one making a mess, etc etc. It's been great.
About midnight I was walking down the hall and heard a cough from her room. Damn near had a ****ing heart attack
