I love this quote.
"To love is to place our happiness in the happiness of another."
"When you smile, I'll smile with you. When you laugh, my heart will beat with joy. When you cry, my soul will shed tears. When you're in pain, I'll wish it was me in your place. But as I do this, my heart's being chipped away. That's okay. As long as you're alive and happy, a little bit of me will be with you."
