Today I rode a subway car within which the AC was not working. While my compatriots and I complained to one and other about our ultimately minor discomfort a woman chimed in, “It’s easy to appreciate things once they’re gone.” For me this was a good reminder to enjoy, as much as I can, every moment of this class. The experience is ephemeral, I am in NYC and seeing many things for the first time. No matter what, even if I end up back here, I won’t be able to recreate this.
