Meeting superwoman

I was standing on the dock, helping customers get on the boat. I was hot and sweaty from the morning sun, wishing for a breeze to come along. I stepped back and slipped off the dock. My life flashed in front of me. Then suddenly, I floated in the air, and then was placed gently back on the dock. Shocked I looked around for my rescuer, and then I saw her. Superwoman. Wow.
