The sand dollar

In the car this morning, John and I talked about going to the beach. He said "I hope I find a sand dollar." I said "That would be awesome. I never found a sand dollar at the beach." He said "I've seen them one time. You know, when the touch tank was at camp. Did you know that they are alive?" I said "No. I have never seen one that was alive." He said "You know what? If I found one at the beach, then I would just put it back in the ocean. Cause it's alive. I wouldn't want to keep it." He has such a big heart. Then he said "You know what? A sand dollar isn't money. You can't buy anything with it."
