photographic memory

Today at lunch I asked Lauren what she learned in Primary. She replied, "Sister Betsy told us a story."
"Oh, fun. Tell me about it."
"I don't remember."
"Okay."
"Except there was a picture of a little boy who was playing on the train tracks and he had his shoe stuck in the tracks and luck-i-ly (she slowed for dramatic effect) he was a very smart boy and he undo'ed his shoe so he could get away before the train came."
