The Anchoress:

I know cops and firefighters who worked the WTC in the days and months after 9/11. If anyone had suggested they take a trip to Vegas to de-stress you know what they would have done? They would have decked you, on the spot, for suggesting such a thing while part of their city lay in ruins, while debris was still smoldering and body parts were still being discovered and retrieved. They would have decked you flat and dared you to get back up and suggest it again.
