"You're sad-looking," she said. "My grandson used to be such a happy boy. He used to write me stories. I remember the first story he ever wrote me, 'Once upon a time, there was a boy.' And that became 'Once upon a time there was a boy who wanted to fly.' And they kept getting better and better over time. I never found out if the boy got to fly." I gave her a small smile. If only she knew the boy's wings had been clipped."
