I absolutely believe in love at first sight...however, I don't believe it is "love" per se, but its an initial spark, an attraction, or chemistry between two people - something that, with time, can definitely lead to real love and is beautiful from the start. Sometimes it leaves you with a silly, lovestruck, ear-to-ear smile that is irremovable for quite a while. Of course, this "love" can also dissipate or be completely destroyed as you get to know the other person.
And then there's another kind of love, wherein you get to know the person first and then start seeing them differently and begin to "love" them through that. All their imperfections are perceived perfectly by you and they seem more and more beautiful by the minute.
Love comes at us in many different ways. Cupid doesn't discriminate! He hits us in different ways...so keep your eyes and heart open and never cease smiling!
