"Be your Valentino just for you."

What does it mean when your mind, or heart, singles out a person out of hundreds? It depicts them out of a huge crowd, and follows this person like a water drop follows your finger on veneer. Is that love? Especially when you have not felt that way before, about a person. I guess might just be. But if it is, what should one do about it? And this person doesn't know you, doesn't notice you, thinks bad of you, cares less about you, or simply does not like you, whatsoever. What then? What power do we have to make them change their minds? And what if that person doesn't even know you feel that way about them? How to cope with this! Love is very powerful...
