Where do these people get off? First of all, I do not care who they are, they have no rights in my house, except as a guest.
I had an aunt who would visit me periodically and every time she would ask me, "When are you going to hang drapes?"
You may find my response rude, but it is no ruder than her question. My response was "Probably never."
Trust me, if I found someone going through my things or cleaning my house, they would be escorted to the door and I would thank them for coming. I would never take those liberties in their home when visiting.
