The quiet after the day finally lets go

It's 11pm and I just realised I've been staring at the same page of a book for ten minutes without reading a word. Somewhere between the coffee going cold and the streetlights coming on, the day stopped being about doing and just became about being. I think that's the part of flying I miss most — that moment when you're cruising at night and the engines are droning and there's nothing left to fix, just the hum.
