I had a neighbor kid next door about ten years ago. He bought a free standing basketball hoop. Before you knew it, all the neighborhood kids were here, and kids from several streets away. They played basketball all day and well into the night during the school week. On several occasions I had to tell them to cut it out, and in a few cases call the cops. One time I was listening to the police officer talking to the kids since I couldn't see anything in the night. It was 10:30, and one of the kids told the officer he was six years old.
I know times have changed, but when I was a kid, your ass better be home before the street lights came on. You better have your homework done, and have a shower or bath, and in bed by 10:00 for school the next day. So where were the parent(s) of all these kids here? If I let it go, they probably would have played basketball until midnight.
