Can an ugly interaction in traffic turn into a teachable moment? He approached my minivan as we were sitting at a red light, watching construction trucks cross the intersection . I rolled the window down, assuming he was a foreman directing traffic. "You don't have to leave twenty feet! If you'd pull up I could get around!" he shouted and then stomped off. "YOU CAN BE NICE ABOUT IT!" I yelled back, as I let my foot off the brake — just a little. In the rear-view window, I watched his white van squeeze by me and cut through the dry cleaner's parking lot to make a right turn. "Did you really say that?" a little voice from the backseat asked. YES I DID.
