I got on an elevator earlier today with a bunch of total strangers. One of them, a friendly kid with big hair and small jeans, looked at the ornate floor and said, “Ooh, it’s like a club. If only we had some fancy lights.” I turned on an strobe light cell phone app, and he began to dance. A woman beside me asked, “Why do you have something like that?” I nodded at the kid and said, “Because of things like that.”
