Love at First Sight?

So literally hours after posting my views on winter bed-warmers, I ironically found myself in the exact situation I'd discussed. Pondering the thought of inviting someone to stay the night, knowing full well it wasn't 'love' that was inspiring this decision, but that void screaming in my head . So I thought I'd experiment with the idea and spent a blissful night soaking up someones arms wrapped firmly around me (the first time in months), and it was GREAT. Ironic..yes! Fate...perhaps?
So continuing this theme of self-prophecy, I wanted to raise the concept of 'LOVE AT FIRST SIGHT'. An acquaintance recently told me of how laying eyes on a girl for the first time in his life, he knew this was the woman he was going to marry. A few years later they are happily married and with child. I'd love to know if this will one day happen to me, and I remain hopeful it will.
BUT DO WE ALL BELIEVE THIS? And does this happen to everyone or a select few, who simply seem better connected to something more powerful and all-knowing then we can even realise? SO...romantic notion or a Disney-inspired concept fed to us as children that gets us through those rough, single patches? Here's hoping for romance on a grand scale!
