This is so weird - the thread, that is. Older threads have very different replies, pointing out it's normal, he's covered, it may be a shared space but it's basically your home, so it's not a big deal. Now people seem to have a problem with it - unless the guy is attractive, which a) is idiotic as attraction is subjective and b ) makes you a massive raging hypocrite. I used to do it - I actually slept naked but put my boxers on to go out of my room. Only two people ever cared, both Indians who were rude enough to move to this country and try to enforce their own Indian cultural morals on English people. I used to stand chatting to girls in the kitchen or dining area, none of them ever even hinted that I should put some more clothes on ("I'll leave you to get dressed and we can chat later", for example).
Seems like people have got a lot more immature since I did my undergraduate degree. Are you all Tik Tok users?
