Come, gentle night, come, loving, black-brown night.Give me my Romeo, and when he shall die,Take him and cut him out in little stars.And he will make the face of heaven so fineThat all the world will be in love with night.And pay no worship to the garish sun…

William Shakespeare

"Anyone who falls in love is searching for the missing pieces of themselves. So anyone who's in love gets sad when they think of their lover. It's like stepping back inside a room you have found memories of, one you haven't seen in a long time."

Haruki Murakami

Do I love you because you're beautiful,

Or are you beautiful because I love you?

Richard Rodgers
