Mr. Olsen found a brown paper bag propped against his office door. Inside was a large, brightly colored balloon, tied with a long, curly ribbon. He lifted the bag, and the balloon bobbed cheerfully against the ceiling.

He walked over to the windows. He imagined himself, floating away from all the paperwork and emails. Instead, he grabbed a red permanent marker from his desk. He grinned.

He spent the next few minutes drawing a silly face on the balloon, adding a jaunty hat and a pair of comical glasses. He propped the balloon on his desk, staring at it for a long while. He felt a ridiculous surge of contentment. It was the perfect antidote to his Tuesday blues.
