On my way to Chinatown this morning, I pass a small kindergarten playground. There are a couple of swings in a large patch of grass but all the kids are ignoring them, looking at the sidewalk though the metal fence that encloses the garden. There is a giant hole in the sidewalk and a crew of two is repairing some water pipes. The kids are clearly fascinated by the spectacle and all of them are completely still, silent as far as I can tell. Ten kids, all about 3 or 4 years old, boys and girl, looking at the work these men are doing. It must look like a giant playground, complete with mud and white pipes. A playground for adults. Irresistible for kids at any age.
