Dear Queenie,
Some time ago we let some friends of ours stay in our vacation home while we were not using it. Then when we went to stay there we found a lot of family photos of theirs hanging on the walls in different rooms.
Queenie, what made them think they could decorate my home that way? And what should I do with the photos?—Offended host
Dear Host,
Probably your guests just wanted to have the pictures around them while they were staying in a strange place, and forgot to take them with them when they left.
Take the pictures down, pack them up and return them to your friends the first chance you get.
