“I’ll be the one with the long white beard,” my old boyfriend tells me. His voice on the phone is low and hesitant, but he’s coming to pick me up right away. Thirty-five years ago he was my first lover, and I am coming back to visit him because I’m alone in England, where he lives, and so is he. His last lady friend has meandered back to her ex, and my last lady friend broke up with me in May. I’ve spent the summer traveling in Europe, and now, at the end, I’ve arranged this spontaneous, short rendezvous with Nelson.
