I used to live in a place where I could hear the distant sound of children playing. It was just far enough away to make it a dim, distant souund (as opposed to an annoyingly close one). It brought me tremendous peace and happiness, like listening to waves at the seashore ot birdsong. Come to think of it, somebody should make a healing CD or MP3 of that sound that you could put on infinite replay and just have going in the background, the way people listen to waves at night to get to sleep or whatever. I'd buy it.
