Today, as I was sweeping outside, I noticed a returned visitor. During the summer, in June, my younger child adopted a little green tree frog that had come to rest on the kids' wading pool. It kept returning, day after day, from across the street. It seemed to like clinging to the side of the pool, and didn't mind being handled a fair amount. The kids took it in, did their research, fed it and watered it and gave it a home. A few weeks later, in July, the frog started to discolor a bit. It worried them, and they decided, reluctantly, that it should be free to be healthy.
