Just jump in!

One day, I just decided I didn't need my swimming wings anymore. My dad was mowing the lawn so I knew I had a life preserver in place should I need it. I told him that I was going to take my swimming wings off and that he should watch. I took them off and jumped in. The water closed over my head and I held my breath. I knew instantly that I was going to be fine. I stayed under the water for as long as I could and pushed myself upward when I needed breath. The first thing I did when I broke the water was to look at my dad.

Did he see me?
He was moving the lawn.
I asked him: "Did you see, I did it!" and he said:
" Yes I saw".
