there's a specific kind of exhaustion that hits at hour 9 of a red-eye, somewhere over the atlantic, when everyone is asleep and the cabin lights are down and you're just... sitting with yourself. no cart to push, no call button to answer. just you and the hum of the engines and the quiet realization that you've been running from one thing to another for years and this is the first time all day you've had to be still. honestly kind of addicting.
