You are in a club alone sitting at a table. You are feeling very lonely and depressed. You look across the room and this young lady is smiling at you and waving you to the dance floor. You get all excited thinking this is your big chance to meet someone. You get up, put a big smile on your face and slowly make your way to the dance floor. As you approach her you suddenly notice that she is not looking at you but the guy behind you. All this time she was noticing someone else, not you. You return to your seat red faced and embarassed. Has anyone experienced this before? I have and it is not a good feeling indeed.
