You never know when your time is going to expire, so remember: as you add years to your life, it is more important to add life to your years.
You know nothing about me, and nothing about the sort of love of which I am capable. Every atom of your flesh is as dear to me as my own: in pain and in sickness it would still be dear. Your mind is my treasure, and if it were broken, it would be my treasure still.
Of course, you never really forget anyone, but you certainly release them. You stop allowing their history to have any meaning for you today. You let them change their haircut, let them move, let them fall in love again. And when you see this person you have let go, you realize that there is no reason to be sad. The person you knew exists somewhere, but you are separated by too much time to reach them again.
