He'd found the boxes in the basement, hidden behind an old workbench. Inside, were the remnants of his childhood: school projects, book reports, handwritten notes. He picked up a drawing of a spaceship, his face flushed with the memory of excitement and imagination.

He closed his eyes, the past a distant echo. The world seemed to have lost its color, and he felt a deep sorrow, a persistent ache for the comfort and love that were now gone. He set the drawing down and stared blankly at the flames.
