Or perhaps to the weight of the keys, but I think that's a weaker correlation.
Keys unlock doors. Keys catalyze. Keys open up dimensions.
Or just locks one into the daily humdrums.
I returned half of my keys some weeks back, and I'm enveloped by an unbearable lightness of uncertainty in momentum space. Where to go from here?
If I spin my set of keys on the lanyard, lasso-style, and let it fly tangential to my peripheral field of view, I can see dragonflies rising from the dews. They dragonflies I see are free, free from the laws of Nature and physics.
My key set flies parabolic across a scrapyard of abandoned space-time fragments. No resistance. It will fly forever.
And I might not even miss it.
