What? Who could do that? Who could let such a rude person get by with behavior like that? Someone practicing Zen living, that’s who. Here’s the thing: In the first scenario, the rude person got away with it anyway. And you spent the next who-knows-how-many hours suffering because you couldn’t let go of the incident. You imagined all sorts of things to explain the behavior of somebody else, something over which you have absolutely no control.
