![]() The other day my daughter finally had a day off work. We decided to go out in the 16 for the time, together! It was an enjoyable experience. Then a surprising thing happened. She turned and asked, “Hey, Dad, can I 17 the boat?” I had a look of fear in my eyes 18 the boat can be driven at a very high speed and can be turned over very quickly. However, I gave the driving seat to her and began 19 her how to properly control the boat. I told her to remain calm as I had completely believed in her.
