The attic felt like a forgotten world, and Leo was eager to explore it. He let out a little whoop as he raced up the stairs. His mother’s penchant for keeping things, which was often a source of teasing, was now a source of sheer glee. This was going to be a grand adventure.

He surveyed the boxes, each one a mystery waiting to be unveiled. He rubbed his hands together, anticipation bubbling inside.

He picked up a box labeled "Science Projects." He laughed, imagining all the exploding volcanoes and faulty circuits.

He pulled out a cardboard model of the solar system, misshapen and imperfect. He grinned. He remembered the smell of the glue. The whole experience would be a blast.
