I descaled the coffee machine yesterday. We live in an exceptionally hard-water area and this maintenance was long overdue.
This morning I turned the machine on and something felt unfamiliar and wrong. I couldn’t put my finger on what, until I realised…
…I’d gotten so-used to seeing the “descaling needed” light illuminated that I’d subconsciously forgotten that it wasn’t supposed to be always-lit! Turns out that a warning left long enough becomes not just invisible but normalised!
(Next, maybe I should do something about the ‘check engine’ light in the car. It’s been on for a while too…)

Similar to when refuse collectors drive around with amber beacons flashing when they’re not actually collecting and absolutely do not need them. Makes them pointless.
