Yeah I had a similar experience back in my college orientation. I was sitting listening to some speaker and this really hot girl looks back up straight at me and mouths, "I want you."
My eyes grew pretty big and I blinked repeatedly, wondering what in the hell just happened. I tilted my head and pointed to myself and she looked at me and said, "no, behind you."
I was kinda disappointed, but then I looked back and the person she was talking to was another hot chick. That made it all better. That always makes things better.
