In my bleary-eyed, non-functional trance-like state, I walked onto the wrong train (the B rather than the Q), which meant a less direct commute than planned, which resulted in me, running several blocks up Park Avenue in uncomfortable sandals, carrying my big bag of drawings.
Meanwhile, the Upper East Side crowd was waking up. They were walking their dogs and talking to their doormen. It was a beautiful Spring-like morning. I wound up being just on time. :-)
