Samantha told John to wear a riding helmet before they took their horses down to the beach. But John could not be bothered to find his helmet and he went out without it. He wished he had when he fell off his horse and banged his head on the shoreline. He was dizzy for days and lucky he didn't hit a sharp stone. Perhaps the experience knocked some sense into his head. We've only got one head. Protect it. Head injuries can hurt a lot.
