I was sitting in my room, reading a book. I heard voices outside. I got up and looked out the window. A house pad, all concrete was poured the day before. It was 6:30 PM and there were no workers around. I saw 2 boys, about 14 years old, skating on their skateboards all over the new concrete, that will be someones house. I got up and went downstairs and opened the garage door. I went out to tell the boys that they should not be marking up the contrete. They were gone. In that “Fleeting Moment” they had their fun and marked up the concrete for a house. Most of the marks were dug into the garage floor area. I would be mad if that was my garage floor. I am sure that the people that bought that house will not be happy when they see it. The builder will probably have to fix this “fun time” the kids had.
