Mr. Henderson stared at the package, a wide grin spreading across his face. It was from Billy, the class clown. A student whose pranks had consistently tested his patience. Now, a package, wrapped in the loudest wrapping paper he could find, had arrived at his door. He couldn’t help but think it was another joke.

He ripped it open, anticipating the typical gag – a rubber chicken or a whoopee cushion, no doubt. Instead, a framed picture of himself, taken during a particularly disastrous school play, was revealed. He was mid-sneeze, eyes squeezed shut, looking utterly ridiculous. He began to giggle, shaking his head.

"Of all the things…" he muttered, and then burst out laughing, unable to stop.
