At the cafe this morning, two men sat down and began ordering breakfast for themselves and their absent companion, who they knew was on his way. The waiter, only seeing to of them, kept trying to squeeze what they were asking for into an order for two, and was getting confused because he couldn't make it fit. Finally, one of the men said, "There are three of us." Immediately, the confusion cleared.
I think many misunderstandings are like that -- we hear each other's words fine, but we are using two different frameworks for understanding what is being said.
