We stayed in a hotel recently. I've since found that my DD (autistic DD) has taken (stolen) one of the hotel room key cards even though it says that they need to be returned when checking out as they are reused for future customers/guests. DD says that she kept it because she "likes it" and "wants to keep it". I think she should return it/post it back to the hotel but DH says I'm "overreacting" because it is just a hotel room key card. AIBU to make DD return this stolen item?
