OPB

Primary Human Occupation: trying to understand Other People's Brains (OPB).

I believe that most of us go through life preoccupied with trying to understand OPB. Every once in a while, you achieve the goal: self-delusion that you actually understand someone else. But even those times will be short-lived. In general, you will learn again (and again) that your mistake was to put too much of yourself into the picture. And then you will be disappointed at best, shocked at worse.

How could this person do, say such a thing? Because they are not like you, stupid-- no one is.
