Shirtless Man Grinding Stones

A shoeless man with a mustache was working at a construction site. Many stones were scattered around him. He crouched down among the stones and was grinding stones with a machine. The surface of the stone was flattened gradually.

The place was surrounded by the noise of the machine. Stopping in front of him, I watched his work for a while. In the meantime, he noticed me and he showed his bashful smile when I held my camera.
