If that is the best definition you have, then I feel sorry for you. Love is simple, complex, wonderful, and horrible all at the same time. It is invisible in plain sight. And for the people that don't wonder and accept it, it makes perfect sense. But for people like yourself, who define it by your own terms, it's true meaning is out of reach. It is best know when not know at all. So why question it when the beauty it holds is never asking?
