When I say something to one of my DDs about DH and my bedroom, I describe it as 'my room', e.g. "please put that in my room". DH thinks I should say "our room", but I think that "our room" would imply a room I share with the DD I am talking to. So AIBU to describe the shared bedroom as "my room"? I know this is really trivial, but I thought MN might be able to tell us who is the normal one.
