When I was a teen and learned with cousins to waterski on the Savannah River, I got up with little ado -- however, I fell and couldn't figure out to TURN LOOSE!
The next time I tried to waterski, I was 40, and mostly did it to show DH that I still could. (I've given up showing DH what a Cowboy I am, eating raw oysters was one of my bravado antics for which my liver thanked me when I quit.) I had trouble getting up until our friend clamped a big hand over my knees and said, "Now KEEP them together," waved to the boat driver and I came right up on the skis, my knobby little knees tight together.
I should have learned these lessons early on:
Knees Together, 1984
The perception of others was pointed up by the reaction of a lady on the river bank who saw my Cousin Herman skiing in a squatting postition, unable to stand without falling: "Oh, look! He's doing tricks!"
