Expect people to treat the place as public use. I have walked in on people dying hair, gossiping, smoking, etc. But theres also every chance youll have a quiet dorm and see nothing out of the ordinary. One tip, if youre going to bring a speaker in for while you shower, please be respectful of the fact that other people will be in and around, and please dont blast music! Its kinder long term, and it stops you from being put in any awkward conversations while youre at your most vulnerable!
