Tbh, this is fairly standard behaviour for students!
I’ve had one dangerously dumb housemate though once! Albeit from the UAE (this was a few years ago) but still, he asked the following questions;
1. How do you dry your clothes when it’s raining outside? (We didn’t have a drier)
2. How do you cook pasta?
3. How do you cook eggs?
I think he tried to cook something in the microwave at one point (likely something with metal) as our microwave was completely destroyed once…
Played his guitar at 3am when everyone in the house was on placement except him (we were all teachers or paramedics).
I wouldn’t take anything they do too seriously personally. I did my MSc this year and each week we had a new (Cu)nt of the Week, randos sleeping in the sofa, one of them bringing back scabbies (I’m not joking, literal scabbies) once every couple of months (as far as I’m aware, he got it at least 5 times in the year and passed it on to all the housemates, minus myself luckily - I suspect it’s because I refused to sit on the grotty sofa!).
So in all honesty, nothing should surprise you at uni!

Random typos!
