I agree with you a 100% the touch and the scent have been MAJOR factors to me too.
Unusual, Hell yes! but yes!! possible!!!
The third point I'm not so sure abt Maria, but i definitely Think the first two are right!
Okay.. so this is what happened to me...
I met him through friends of friends... and for some reason, i had to get closer; which i did. when I shook his hand, this feeling overwhelmed me, on an impulse hugged him. It wasn't a party, it wasn't even a get-together with friends, this was just information gathering about a college i wanted to get enrolled in. so the hug was wayyyyyyyyyyyyy off and frowned upon. for some reason, that didn't matter. My mind was immediately made up as to which college i would be attending. met him again after 3 months. and there it was... the same impulse to get closer, the same feeling of wrapping my arms around him as soon as our hands touched. I didn't want to go another moment without having them... i still dont want to go another moment without him assailing my senses
I've always been a 'hugger' and i've hugged other guys before, people i thought i had 'interest' in... But like Paya said, something was missing. something was ALWAYS missing.. something was complete when i looked at him, shook his hand and drew him into my arms : D
So, yeah, for me... Love at first sight is VERY real... and it definitely exists!
