Anyone up for Tennis?

I think this is what they would call "Protagonize Tennis." Basically I wrote a very short bit about a character and I want us to continue writing on his story.

• It could go any direction. But once it's in a certain direction it should stay that way. Unless there is a chance for a smooth transition.
• No mature content
• Don't hog the story by having a giant chapter that leaves others having a hard time branching off from.

I think that's about it. Oh and have fun.
