!!!!

I've met a few friend's at terminal having lunch. While having lunch, there are one of my friend's friend come over and approach him. He was so amazed with that girl and she said, 'where have you've been all this days??You know that we can have a good chat if you're going out with me?. He keeps on praising the girl so that he can go out with her. I was listening and i smile a bit. Why he is so desperate?hehehehe...I just can relate this situation to a fallacy which is called Ad Populum appeal to vanity.
