I had a new flat mate move in a few days ago. They haven’t showered since being here. Whenever they use the bathroom it smells of unwashed person. They’re also a bit messy but I’ve overlooked that so far because I’m a clean freak. But I’m really struggling with the fact that my home now smells of dirty smelly person! When you walk past their room it smells even more strongly. Is there anything I can do to broach this or make it better without being rude? :(
