 What's been your biggest surprise sort of moving out from the centralized role of OMB to an agency? You've been in government for a long time, so it's not necessarily going to be, I would assume, something that's sort of, oh, I can't believe it's so hard to get into the buildings or things like that. But what about Social Security specifically has sort of surprised you and has energized you in the work that you're doing right now?
