How have I missed this thread?! We have:
1) The guest who never locked the bathroom door while she used the facilities and then acted indignant and offended when other guests opened the door. ("Did you realize someone was in there?" "Couldn't you see the light under the door?!" "I shouldn't HAVE to lock the door, it's up to you to check if the room is occupied!") She made such a fuss, it made the rest of the evening really awkward and uncomfortable. She did this at two events, refused gentle prompting that she lock the door behind her. ("I shouldn't have to lock the door. Just let everyone else know I'm in the bathroom if you see them heading down the hall!")
And just last month:
2) The guest whose son was incredibly immature for his age, 7. He let a stuffed frog "speak" for him. He insisted all of the adults at a dinner at our house pet and speak to the stuffed frog. He went into our 2 yo son's room and saw that DS has a stuffed frog I'd just brought back for him from a trip to NYC. The frog was on top of son's dresser. He climbed up on the dresser and dragged it down.
6 yo DD, who is very protective of brother, protested and Guest's Son shoved her to the floor. She chased him around the house, trying to get the frog back. He hit her several times before we caught up to them. Guest's Son pitched a huge tantrum when I took the frog. Instead of disciplining him for hitting my daughter, his parents said, "Well, frogs are his thing." which I guess means no other children within a 50 mile radius are allowed
to own stuffed frogs.
I took the frog and put it in my closet, where Guest's Son couldn't get to it, then returned to cooking dinner. I heard a crash and realized Guest's Son had gone into my closet, stood up on a shelf, and knocked down a rack of shoes to get to the frog.
His parents did nothing to correct the behavior, except to say, "Couldn't we just share the frog?" and it took me a minute and several more comments from them to realize they meant they wanted me to give their son the frog! I explained it was a gift to my son, that it wouldn't be possible. Mom huffed, "Well, in our family we share with guests." I put the frog in my locked car and will never invite them to our house again.
