Why I don't believe in love at first sight?

There's no way. I'd say it's next to impossible? My friend argued me that when you look into some one's eyes you can see their "soul." I'm like ( o _ 0 ) yeah right. Cynical? Yes. Why? Because in order to really love some one, you have to get to know that person. Love at first sight to me is "lust" at first sight. What do you think?
