love at first sight ??? Yes...
It is just like a fire spark.. significant but short...
Usually, it is not the looks that attract one... it is the small
actions that he or she does or the aura that lead one to think she
may be the one...
I leave that type of love there... y??? dont noe how to
approach... 
I think these type of 'instinct-based' kind of love may last
long... provided the attraction tat u think he or she has are
really true... Not fake....
