Liam stared at the email, the words blurred. The rejection stung, but then, a strange lightness bloomed in his chest. He tapped his fingers on the desk, the rhythm mirroring the rapid-fire beat of a song stuck in his head. He began to hum along.

He stood, did a little jig, and then began to spin in circles. The room blurred; the disappointment evaporated. He imagined himself swinging from a chandelier, just for the fun of it.

His stomach rumbled. He needed a snack. With a spring in his step, he headed towards the communal kitchen, deciding to make the most ridiculous, unhealthy sandwich imaginable. Peanut butter, jelly, bacon, pickles, and chips all crammed between two slices of white bread. The worse it was, the better.
