“Ugh,” David muttered, the word a weary expulsion of breath. Every muscle in his body felt sore, and his mind felt fuzzy. The relentless demands of the day had taken their toll. Even the short walk to the mailbox required more effort than it should.

He found the usual assortment of bills and junk mail. And a card. It read, "Happy Birthday!" in a bouncy, childish scrawl. No name.

He sighed, the sound echoing in the otherwise quiet street. He'd hoped for a little bit of recognition, a small sign that someone cared. The lack of context made it feel even more hollow. He let the card fall from his limp fingers.
