I like tennis. Tennis is fun because it challenges you. I like tennis because it is fun hitting the ball over the net. Another reason I like tennis is because you can play doubles with your friends. Tennis is a sport you can play for your whole life,even when you are older than 90. Tennis is a good way to get exercise, and have fun. It is not like soccer, where you have to have a lot of people to play. You either have two or four people to play tennis.
