   Adam was a perfectly satisfactory dinner companion, if not a bit damp and blandly lecherous (he revealed he had looked at my Instagram before we met and “really liked the photos of me in a bathing suit.”) And now, standing on the street corner, it was unclear how I was going to walk away from this without an awkward shutdown. 2016-03-21, Allison P.
