There was once a little boy who was bored at the beach. He went for a walk along the shore and eventually came across a funny sail and board contraption. The lady whose windsurfing kit it was came over and explained to the little boy how it worked. She offered to teach him how to sail. Having nothing else to do the boy readily accepted.
After a few goes the boy was managing to uphaul the sail and glide back and forth. Turning was still a tad tricky but the lady explained practice makes perfect. Within a week the boy had gained much more confidence and his windsurfing skills were progressing rapidly.
