The tennis court (Anyone)

It was Sunday and thank God, I was free. So I thought to do some sport, as this was my favourite thing to do in my spare time. I had seen a tennis court a few days before, so I decided to go there. Tennis had been my favourite sport since I was a child. I loved to play it, to watch it, to write about it, everything. I didn't bother to find a partner, I just went there to practice my serve. It had been about 30 minutes practicing, when I heard footsteps behind me.
