Also do you have no door because your parents are afraid you might do something with your brother/sister?
You're hardly one to make jokes about the state of anyones house.
I don't mind sleeping naked, but I don't do it much.
I think because I don't do it often, I find it more difficult to get comfortable.
And while I always have my door closed (or locked at uni), I worry that someone would come into my room while I'm naked.
Typically, I just sleep in underwear. Sometimes, but often not, with socks.
I thoroughly dislike sleeping with pyjamas on, although can do it.
I just spent a week staying at a friends and sleeping in their bed, so I wore pyjama bottoms the entire time. It was uncomfortable, not least of all because it just got so hot.
