The air clung to him, heavy and oppressive. He approached the mailbox, his steps slow and deliberate. A card, brightly colored and conspicuously out of place, waited inside. It was not his birthday.

He spent the rest of the day staring at the wall, paralyzed by a sense of loss he couldn't name, a grief that had no form.
