Castle Quotes

Sometimes the hardest things in life are the things most worth doing.

Castle

The moment we met my life became extraordinary. You taught me more about myself than I knew there was to learn. You are the joy in my heart. You are the last person I want to see every night before I close my eyes. I love you Katherine Beckett and the mystery of you is the one I want to spend the rest of my life exploring. I promise to love you, to be your friend and your partner in crime and life till death do us part and for the time of our lives.
