On a sunny day, Kelvin and his father go to the park to play golf. When they are playing, suddenly, the ball falls into the lake with the duck on the water. Then, it gives back to Kelvin and he is very happy.

At weekend, Alex goes to play golf with his dad. When they are having fun time together, the ball falls into the lake near there. A duck is sleeping but he is waken up by the ball. Luckily, the duck gives back the ball to Alex. What a kind duck! Alex thanks him for that so much.
