“It is like a beautiful sunset you see once in your life, one you swear you will never forget as long as you live. And you never do forget, but you never have a reason to restore the memory—so it remains hidden inside. Until one day, for no apparent reason, you remember that sunset. You recall the way your skin felt as the sun brushed across it, the way the colors painted the sky. You wonder why it took you so long to go back to that place again, swearing you won't take so long next time. Only you do forget the memory and you may or may not ever relive it again.”
