He unearthed a box labeled "Leo's School Days." He popped the lid. It was a cornucopia of his past โ€“ essays, art projects, spelling tests. A wave of joyful anticipation washed over him.

He picked up a crumpled drawing of a spaceship and felt the corners of his mouth lift. He remembered making this. It even had little aliens inside. He held it up to the light, smiling.
