The rhythmic thud of the hammer felt like a secret code to Henry. He darted out of the house, his feet barely touching the ground. He had an urge to be involved.

He found a discarded piece of wood and began to draw on it with a large black marker, creating a series of absurd faces. He carefully propped it up against the fence, then waited.

The construction worker noticed, and his face broke into a smile. Henry beamed back, his whole body buzzing with a delightful anticipation. He then grabbed another piece of wood, and resumed his impromptu art gallery.
