i used to play tennis a lot, actually. When i was young, i lived at a place ad some tennis courts in the apartment complex. And they would have some tournaments for the people who lived in the apartments. I got pared with a woman to be my tennis partner who had never played tennis. Now i said to myself, it looks like i'm going to lose this tournament. Im playing with somebody whos never touched a tennis racket. But i don't like to lose. So i set about the task of what would it take to win if you have the players never touched a denis ball? It's really rare. Almost nobody can do that, but she could.
