Love At First Sight

I've heard this almost every where; in movies, books, and in real life. And when people say it I can't help but laugh.
'From the first time I saw you (insert name here) I knew I was in love'
Really? Is that even possible?
In my opinion there is no such thing as love at first sight. But there is such a thing as Lust at first sight. When you first see a person what do you notice? their hair, their eyes, their lips, their body. When you walk into a bar you don't turn to your friend and say 'hey look at the personality on that guy!' No! its more like 'Hey check out the hot guy standing at the bar'
Love at first sight doesn't exist. People usually fall in love once they get to know the person, see their personality and what they like about it, and how they make them feel when their with them. You can't get all that from a glance. And that's why some movies have it right. There's that geek boy who is infatuated with the popular girl in school and when he finally gets his date with her he sees her for who she really is and changes his mind.
Love at first sight seems like a sweet thing when you think about it, but then you realize the true way of deciphering it. But hey maybe I'm wrong and when people say it they do mean it.
