We have builders in replacing a couple of windows. They stated this morning. I have just found one of them sitting in my ensuite bathroom, muddy work boots & all, reading my OK magazine and having a dump. I only knew he was there because he work up my sleeping 3 month old baby closing the door. AIBU in expecting him to either a) ask before he uses the loo and b) expecting him to use the downstairs toilet? When I said this too him he looked at me like I was quite mad. AIBU?
