They never see each other again.
They never forget each other either.
They live in their own worlds, but they also carry a part of the other world in their hearts.
They grow older and wiser, but they also keep a part of their youth and curiosity in their minds.
They face many challenges and opportunities, but they also remember the lessons and experiences they shared in the mirror dimension.
They find happiness and love, but they also feel a pang of sadness and longing for what could have been.
They are content and grateful, but they also wonder and dream about what might have been.
They are John and John, but they are also more than John and less than John.
They are themselves and each other, but they are also more than themselves and less than each other.
They are something that is human.
