On Tuesday she showed me her secret. “I grew them when I was in college,” she said.
  She kept them tucked beneath her tank top, between her shoulder blades. Diaphanous, they looked a little like those of a mayfly, or a damselfly: pale, iridescent. She didn’t want to tell me she had grown them. Maybe I would think them freakish.
  “I grew mine when I was 15,” I said. Mine are dusty blue, like a scrub jay’s.
