I was running to catch the northbound subway this morning when I passed some buskers and saw a man dancing. He was in his 50s, he had a briefcase, and he was dancing loosely to the rhythm of the Spanish guitars.
I didn't stop to join him. The doors were closing, and even as the loudspeakers warned that one shouldn't jump through the doors I did. As I settled into a seat, I heard the man calling, yelping, "Wait!"
