No, but I get a mysterious message

The events of the party are still on my mind when I sit in my room, reading a book a week later. The next day Josh had told me that what had happened was the only thing people talk about. The next few days I hung out with Josh a few times and we got along pretty good. It is a relief to find someone to connect with in a new environment.

Just when I am about to start a new chapter I get a message on my cell. I'm putting the book aside and take out my cell. The message is from an unknown number.

“Hi John.” it says.
“Who are you?” I type and send back. It doesn't take long and I get a reply.
“Someone who will make this night unforgettable for you.” it stated.
“Look out of the window.” the next message appears before I get a chance to write one myself. Sliding my cell into my pocket I get up and walk over to the window. In the first moment I don't see anyone. Then someone appears from behind the big oak tree.
