Her guests are now my guests.
Since my MIL (dementia) moved into my house, her only surviving child (my deceased husband's brother) stops by to "visit." I should be happy about that but he never calls ahead of time......just pops in at odd hours. Then he stays and stays .......talking to me - not her. If I leave the room to do something else, he follows me!! So just venting, when she moved in - her "visitors" did too and that's something I didn't even think about previously.
