Don't Swallow Your Harmonica

I'd never seen such a tiny harmonica. When my father-in-law put it to his mouth, I thought for sure that if he hiccuped, he'd be playing "Auld Lang Syne" in his sleep with every snore.
After a rendition of "Oh My Darling Clementine," he said, "Amazing, isn't it? I can play a song with just four holes."
"That is amazing," I said. "It's also amazing that you can keep hold of it. You could use that thing for a tie tac."
Dad lifted up a slender, silver chain that draped down from the end of the tiny harmonica. "Do you see this?" he asked. I nodded. "I keep it on this chain in case I accidentally swallow it. Then I can pull it back up."
I had to laugh. It's good to have a plan.
