> We get old and get used to each other. We think alike. We read each others minds. We know what the other wants without asking. Sometimes we irritate each other a little bit. Maybe sometimes take each other for granted.
>
> But once in awhile, like today, I meditate on it and realize how lucky I am to share my life with the greatest woman I ever met. You still fascinate and inspire me. You influence me for the better. You’re the object of my desire, the #1 Earthly reason for my existence. I love you very much.
