Defining love is like describing a color to the blind.
You might say, "Yellow is happy. It is the sun, a daisy, a duckling."
You might say, "Red is passionate. It is a rose, one's heart, an apple."
But these are elementary, trivial words. They are pointless. The blind will only memorize your words. They cannot truly know them. They cannot truly know That grass is green, a bluebird blue.
In fact, You could lie to them. And most people will.
Color can only be seen, just as love can only be experienced, never to be conveyed in its true form to others.
And trust me. Falling in love is like seeing colors for the very first time.
