In South Street Seaport in New York City, they close off the last pier on certain days and put on music so couples can come and dance... most people dance the tango, and some people just dance. People dancing in the middle of the city chaos just stands out so loudly, you can't help but notice them - but they are totally in their world, not noticing you at all. Really - everybody else might as well not be there, including the Brooklyn Bridge in the background - all they need is the music....
