There is a specific kind of rest you only get when the pager belongs to someone else. Not a long holiday, not a grand escape. Just a normal Saturday where I know, with certainty, that if something falls over it is genuinely not my problem to fix. I had one of those this weekend and I had forgotten how much lighter the air feels.
On rotation, even a quiet weekend isn't quite restful. You keep the phone within reach. You don't have a second drink. You half-listen for a buzz that mostly doesn't come, and the not-coming somehow costs you almost as much as the coming would. It's a low background tax on your attention that you stop noticing until it's lifted, and then the absence of it is startling.
So I did very little, deliberately. A long walk in the cold with no destination. A book read in one sitting because nothing interrupted it. Cooking something that takes hours rather than minutes, purely because I could give it the hours. None of it productive in any sense a timesheet would recognise, and all of it exactly what I needed.
I have come round to thinking that protecting this isn't indulgence, it's part of doing the job properly. An engineer who never genuinely switches off makes worse decisions, debugs more slowly, and gets a little more brittle each rotation until something gives. The good teams I've worked on understood that on-call is a cost you pay people for, and that the time off the rota is not a bonus but the thing that makes the time on it sustainable.
The pager comes back to me next week, and that's fine. That's the deal. But for two days it was elsewhere, and I let myself be properly, uselessly idle. I'd recommend it.
