Return to the Scene of the Crime

On Monday I returned to the library for the first time since retiring.  Had to pick up some stuff.  I was rather surprised how unemotional the whole thing felt.  Met the new librarian who has my old office (but not my old job).  Said hi to some friends.  But no sense of "Ah, the old haunts."  Too soon perhaps? 

One odd thing I noticed was that I was much more low key, soft-spoken, than I usually was at work.  No idea why.  Not projecting a persona today?
