He felt buoyant, almost giddy with happiness. His laughter bounced off the walls as he thought of what the future held. He grabbed his journal, eager to chronicle the joy he felt.

The journal was on the floor, slightly askew, with several pages dog-eared. His face fell. He stared at the page detailing his secret crush on someone in his class. He noticed his roommate, Kevin, attempting to whistle a jaunty tune, but the effort sounded forced.
