Mother says, "Pick it up and I'll take a photo of you holding it."
I am indignant. "Verboten," I say. "If you touch a butterfly the dust gets rubbed off its wings and it won't be able to fly. Koch says."
"Well, Koch is wrong. Pick it up. You won't hurt it, I promise."
"But Koch SAYS!"
"Koch is not your mother. I am your mother. Now pick up the butterfly and I promise you with all my heart that picking up a butterfly will not hurt it. It will fly away, I promise."
I pick up the butterfly, holding it gingerly at the tip of one wing, hoping not to rub away the magic dust. Mother snaps the picture. Relieved, I release the butterfly. It falls heavily to the ground, smashing my innocence. The photograph survives.
