No shame is quite so stinging as that felt after fuming at the sheer effrontery of the fates in inconveniencing you -- yes, important you, with places to go, people to see, things to do -- with maddening stop-and-go traffic on the interstate, and then you come across that nasty accident blocking part of the road and it occurs that some people might have it worse than you today after all. Perspective, self. Perspective. And maybe a Hail Mary, too, while you're at it.
