John stared at the letter, its yellowed paper crackling softly. He’d found it tucked inside an old book belonging to his late father. The words, addressed to his father, were a confession of inadequacy, a teenage boy's lament about failing to live up to expectations.

He ran a hand through his hair. The sting of past failures felt distant now, almost insignificant, in the face of what he'd achieved. He held it close, inhaling deeply. A smile tugged at his lips.

He looked at the letter again, and saw the raw vulnerability of his younger self. Tears welled up in his eyes. He felt a powerful urge to hug his own son, not because of anything specific, but just because he could.
