I've always wondering about street lights and lamps and how we interact with them. Sometimes me and a friend or two would be out and about walking, usually at school or around the neighborhood. We used to notice them going out at our approach or just as we got right by them, then they would click back on after a bit of distance was made. It was only certain ones, not a whole bunch. Cant remember it was only specific ones or if it varied/rotated. We figured there was some kind of interaction taking place between us and them, like a psychic or energetic field disturbance. Never really quite understood it, but thought it was kinda cool and odd though, hehe.
