A chuckle bubbled up from within. He hadn't expected this. Not ever. He wondered if old Mrs. Henderson, the recipient of his misdeeds, knew how much he'd agonized over writing this. He'd envisioned her reaction. He'd even rehearsed his own response, in case she decided to come knocking. The anticipation made him want to explode with energy.
