I'd love to learn how to play tennis! It looks like such a fun sport. Have you ever played?
Yes, I have!  It's exciting that it is an Olympic sport!
It is?! I never realized that! Do you usually play with four people or can two people play?
I usually play against one person, though sometimes a friend and I get together with two others and play doubles.
That sounds like fun! How do you score points in tennis?
If your opponents hits the ball to you and you don't return the ball, you don't get a point, but your opponent does. So you need to hit that ball back!
