He felt an odd flutter in his chest, a sensation that almost tickled. He pictured the reactions of his friends and family. The sheer absurdity of it. He began to walk.

He quickened his pace, a spring in his step. People pointed and gawked. Arthur just adjusted his glasses, and a wide, secret grin blossomed across his face. He knew he was the only one in on the joke.
