A childhood belief about around the house

When I was little, my family and I would rent a house on the beach in the summer. Every year we would buy kites to fly. My grandmother would tell me and my brother that there were tiny people living on the kites and when we flew them too close to the house, they would jump off and run around on the roof. That was her way of explaining why the roof creeks at night. It was years before I understood the concept of materials expanding when they got hot and contracting when they cooled off as in the roof cooling off at night. Even now, as an adult, when the roof creeks on my own place, I think "Must be those 'Kite People'". LOL
