It is still comforting, of a fashion, to think about my Leah, though such thoughts come attendant on the usual wave of grief that my Leah is not who I have with me now. My Leah was funny and strange and predominantly wore men’s underwear. My Leah chewed hangnails loudly and knew the name of every actor yet never remembered the words to a song. My Leah took me out to the beach near the nuclear power station where she’d used to go walking with her father—haar fog in January, too cold and too early for anyone to be there but us.
