New Swimming Skill

Today I went to YMCA for swimming class. Before the class, my Dad asked me:" Do you want to play water bomb?" And my Dad threw me in the water and I came up and my Dad said:" Let's learn a new swimming skill." And my Dad said:" first you take a deep breath, then you put your head under the water, then you swing your legs up and down to slap the water." I made it to the other side of the pool. And then I felt happy. After that my swimming class began.
