You turned into another. You turned into nutter. You turned into another man.

Is it possible to know another person, inside out, upside down?
You may be able to finish their sentences, but could that be put down to a more 'routine' element.
And would you ever want to know a person that much? Would that create a very balanced sense of peace in your life, or would it be a catalyst for fear. Fear that there's nothing else to live for?
