Jeff wanted to learn how to surf which isn’t as easy as it looks. He had a surfboard and a wetsuit that he borrowed from some friends. It was easy to stand on a surfboard when it was resting firmly on the sand. When he tried standing on a surfboard once it was in the water bobbing up and down, that was much harder!
