I loved this essay on layovers. Airports are usually incredibly relaxing for me:
All sorts of big questions wait on the other side of the gate. Will Bill still love you when you get home? Will you make it out there at college? Will Morocco be everything you’ve always dreamed of?
But you don’t have to answer questions like that during a layover. You can’t: The whole point is that they have to wait. You have been granted a reprieve — a chance to consider life as it was before it goes away, or as it might be when it arrives.
