That is an amazing quote. Life is like a piano, the white keys represent happiness and the black keys show sadness. But as you go through life's journey, remember that the black keys also create the music.
I remember this part of the movie. Tht one word "forever" yes they r no longer together. It doesn't seem like they might get back together or married for tht matter but I can't help but feel tht they will love each other forever.
