Supreme Court Justice and the President's Counsel? Come-on?
I heard on Fox that in her years in DC, Miers has never gotten into that scene; I forget who was reporting, but he said that might be part of the reason Bush trusts her not to change.
Conceivably there may be duty things that they'd all have to go, but such an event would probably be large and the social obligation be only to put in an appearance. Though not being part of DC social scene myself, I can't speak authoritatively. ;-)
