He imagined the reactions of his former classmates. Their surprised looks, their envious glances. He pictured himself regaling them with tales of his adventures, exaggerating slightly, embellishing just enough to make things interesting. His shoulders shook with silent laughter.

He grabbed a notepad and began sketching out a costume. A ridiculous, over-the-top costume. He scribbled a mustache, added a monocle, and underlined the word “triumphant” three times. This was going to be fun.
