Michael practically bounced in his chair when he saw the return address on the envelope. A hand went up to his face, covering his mouth. He thought to himself, 'this is the day!'. The anticipation that he felt was almost overwhelming.

He ripped open the envelope, the paper crinkling with a satisfying sound. His eyes scanned the invitation, a grin spreading across his face. He felt like a coiled spring, ready to release. His mind raced with ideas.

He leaped up from his chair, a sudden burst of energy coursing through him. He walked over to the mirror, winking at his reflection and then began to do some stretches. A rush of excitement bloomed in his chest, making him feel like he could run a marathon. He glanced at his calendar, already plotting. It was time to relive the glory days!
