Some people carry umbrellas so long they forget sunshine was ever part of the forecast.

Vigilance that once made sense can outlast the weather it was built for. Someone who spent a long time in difficulty learns to expect it, and that expectation continues after the conditions change, filtering out evidence that things are actually all right now.

Check whether your readiness matches your current circumstances or an older set. Try one day of not preparing for the thing to go wrong. If it feels dangerous, that is worth knowing rather than obeying.
