Doctor to me:
"I've had to tell people they're going to die and see them realize that they've just been existing, and I've had the privilege to watch people die - and it's nice to meet people like you - who are already really living their lives with intensity and meaning."
and, later that night
Random guy, Dan, to me, while waiting for the tube:
tentatively, "Are you famous?"
That should last me at least a month.
