We ended up staying on, talking and dancing, connecting and disconnecting, for four hours. We chatted with Pratt students in Bed-Stuy, with a man inexplicably sitting on his toilet, with a kid waving a gun and a knife, and with a guy who went to my wife’s old high school in California. We saw Chinese kids in computer cafés and English kids drinking beer. We danced with a guy in his bedroom to the entirety of Michael Jackson’s “Don’t Stop ’Til You Get Enough.” We talked for half an hour with a 28-year-old tech writer from San Francisco.
