At this stage, apart from my medication, I worry the most about my devices and chargers. Everything else, from toiletries to clothes I can buy if it turns out I forgot it and really need it. That lowered my stress with packing significantly (and I am not forgetting more things because of it).
Sadly, this was a thing even before the web, let alone social media. There’s always been people for whom the vacations didn’t even “happen” unless they get to go on incessantly about them when they come back, ideally subjecting you to two hours of photos that mean very little to you. They derive little enjoyment from actually being there, they take it from showing it others…
For some people life is not worth living without external validation. Sad.
