I hosted my friend yesterday for coffee and a catch up. She excused herself to use the bathroom a couple of times (which I’d cleaned before hand). When I went to use it after she left, I was greeted by an extremely messy scene. She had obviously had an upset stomach but made no attempt to clean after herself nor mention it to me. Is it wrong to call her a CF?! I wouldn’t dream of going to someone’s house and leaving it in such a state.
