You know you really know someone when you can have an argument with tht prsn all by yourself.

You start the quarrel in your mind, know exactly how he would retort you. In your cranial conception you rebutt him, and he makes a comeback. You never see his side nor he yours.

You know the quarrel would have no compromising end and a fruitless venture.

So you don't start the quarrel afterall.

Him, btw, is a hypothetical entity.
