I had one almost that long last week. My partner actually walked on the court to show the players the boundry and center lines (and they were very clearly marked). He also went on to describe how a player can play a ball and then go up into the bleachers but if the player stepped on the bleachers first and then played the ball.......and so on and so on.
I almost fell asleep. Oh and he stood opposite me instead of on the same side and he had his back to the court. Maybe that is why he had to walk over to the lines and explain them
