When you were a freshman you went on exactly two dates with a professor from Sarah Lawrence. It was almost midnight the night before Valentine’s Day and you and your friend were leaving the library and decided to go have a drink at a bar near campus. It was cold outside, and when you laughed you could see your breath. And the bar, which on the weekends was packed with students, was nearly empty that night, so you ended up talking to a couple of 30-something-year-old men, because they looked cool and spoke French and rolled their own cigarettes.
