OOOkkkk guys!! I read most of the answers here and it just says "NOPE" or that it is "LUST AT FIRST SIGHT". Well I dont blame them. No matter what anyone says these things actually have to happen to you for you to believe. And believe me, I actually didn't believe in it myself. But you know what they say,, destiny can give you pretty harsh lessons, and I actually fell in love with a girl at first sight. We have been together so happily for the 3 years now and we hope to get married next year...
Well how do you know that it "is" LOVE? Hmmm.... its really hard to explain but you'll know in an instance that it is love. The feeling is really hard to miss-out. So if you have had this unexplainable emotion, well, no matter whatever others say, it is love!!
And believe me people who fall in love at first sight have MUCH better relationships than the others. Thats because you already know her. (Oh, nd this is one of the feelings you get when you are in love)
So, dont worry what others say, just follow your heart.
This answer might have sounded a little fairy-tale like but those who know, know that every word is true!!
Cheers, and good luck!!
