Just sent this shot to
vjsmom, who is, right now, the oldest person in the Caribou Coffee she's in somewhere in or near Rockville, MD.

That made her the second oldest person in there. Sort of.
Under what sorts of circumstances do you, reader, find yourself thinking, if you ever do, something like "I'm the oldest person in here" or "I'll be the oldest person there" or "I hope there's somebody else there somewhere near as old as I am"? Answer with "young" for "old" if that's more appropriate.
