Snail sanctuary?

Declan and I were doing yard work. I found a snail shell. I thought it was empty and showed it to Declan. He put it in his pocket. A few minutes later he noticed that the shell and his pocket had started moving. He took it out and was amazed to see there was a snail in the shell. He put it down on the concrete and watched it crawl all over. He was absolutely thrilled to see the snail moving slowly along the ground. He would look at it and yell wow and go go go.
He doesn't know that his mother doesn't like snails. I murder them. Maybe Declan will start a snail sanctuary.
