“Thank you.”

There is a discipline you learn in emergency work that is very hard to explain to people who have never needed it: how to feel nothing at all, on purpose, for as long as the crisis lasts.

You do not have the luxury of your own fear when someone else’s life is in your hands, so you learn to set it down in a locked room and go on functioning without it, and you get so good at it that eventually you can do it for your own crisis too.
