I agree.
Living with other people can either be loads of fun or a complete and utter nightmare.
I’ve only done this in uni halls. I was unfortunate to be living with someone who was really horrible. I avoided this person as much as I could, which sometimes wasn’t possible. I never went in the kitchen and always made sure the coast was clear before leaving my room. I absolutely dreaded returning to the flat when I was out because I’d never know if someone was in the hallway. Sometimes I would deliberately not go back until after midnight, fortunately there was a lot to do on campus (I went to the student bar a lot, became a bit of an alcoholic).
In the end I just moved into different halls without even telling my flatmates (during the Christmas holidays when no one was there). Was a bit awkward bumping into one of them afterwards.
I hated the experience (yet I have weird feelings of nostalgia for it). The most annoying thing was that this person already lived in the city of the university, so he didn’t even particularly need to be there.
