When my sons were still little my brother and his wife came to visit. They had no kids, and I think they had become a bit old for their ages.
My sons were learning to throw Ninja stars, and I had put some celotex up on a wall at the end of a hallway. There were gouges in everything where they had managed to miss the celotex. Our guests did put in the planned time of visit, but never came back.
I could tell more strories about visits from people who might have been expecting normal, but didn't find it. Some of them still mention how weird it seemed, 20-30 years later. And believe me, they do talk and dissect everything. Don't you
"God, did you see what they expected us to eat?" Etc
