Approaching Union Square

One at a time we meet 11 people in the hour or night before they board a morning cross-town bus in Manhattan. Some have been engaged in significant conversations: talking to a psychiatrist about premonitions, breaking off an affair, working out internal issues. We see others being trivial or self-absorbed: a hound with an STD, a woman with a large phone bill, another who may have met Mr. Right. After we've met all 11, we join them on the bus. One has what may be a seizure. What's going on?
