The morning sun cast long shadows as David carefully sorted through his uncle’s possessions. The air crackled with anticipation for the weekend ahead, a planned trip with his friends. He’d managed to finish a daunting project, leaving him feeling buoyant and eager.

He stumbled upon a wooden box containing various documents. He picked up a letter with his uncle's familiar handwriting. He recognized the sender: "Ms. Evelyn," his uncle's former boss. He felt a flutter of excitement. The letter was a draft.

The letter was filled with witty observations and an unusual degree of self-awareness. He was leaving. A grin spread across his face as he read. He imagined his uncle, always the life of the party, making the decision. He felt his face warm with affection.
