I had to catch a 7:55 p.m. flight from JFK to SFO, and since I didn’t want to sit in a cab for hours on end to get there, I took the A train. In the end, it probably took longer, and I’m still not sure that I was on the correct A train, but I got a crash course in subwaying. (I was also warned by a coworker not to ever say I was going to the subway place outside of the closed elevator I said it in.) I’m glad I took the train. It was an exercise in calmly letting go, since I still wasn’t to the airport an hour before my flight was supposed to take off. I met people who helped me, and a couple I helped, and had tiny, abbreviated friendships with them.
