What did history teacher deborah hargis recalls about Mike wenchell?

From the text:

The year before, when he had been in her history class, they had held a Beautiful Baby contest. Mike brought in a picture of himself, but it wasn't one of those smiling-fromear-to-ear shots taken at Sears or Penney's. Mike had never lived a life like that. Instead he was holding a piece of gum while a single tear, like the wispy trail of a jet, fell down his cheek. Mike explained that he was crying because he had never seen a camera before and thought it was a gun. Hargis always remembered that picture and the softness of those brown eyes as Mike apparently thought he would be shot the second the shutter button clicked.
