He did this for hours today. Filling up his pail with sand and dumping it in the water and back again. He also started immediately upon arriving, as if it was his sole mission and he knew it. Then, he would switch it up and dump the water from the ocean onto the sand. He stared at the other kids around him, but was not influenced to copy them or abandon his mission. I watched him instead of resting or napping. Couldn't take my eyes off of him. He had me mesmerized.
