Umbrellas are less like physical items and more like Higgs fields in Japan. They exist as a probabilistic continuum, and materialize when you need them.

Said another way: let go of the notion of “your” umbrella, and just accept that when you do occasionally purchase one, you’re inserting an umbrella into a broader system.

I’ve had people come running out of their houses to hand me umbrellas on a rainy day; they really are a social good.
