We're at the beach and dad has caught this lizard, something like an alligator lizard whose size increases until it is eventually the size of a cayman and then even bigger. The thing is that he caught it somewhere else and brought it to the beach. Now it's crawling around on the rocks and piles of seaweed and I'm afraid it's going to die. He catches it again and holds it up to me repeatedly with a self conscious expression on his face. Show and tell.
