Our lives revolve around a constant expectation of what *should* be.
We make decisions, take actions, and base our entire existences around what we predict *should* happen.
When you open a door, the handle, should turn, it *should* swing, and you should be able to walk through.
And there *should* be nobody on the other side.
We've all witnessed what happens when these presuppositions aren't fulfilled.
People follow through with their actions.
Walk right through the doorway, and collide, or almost collide with other people, depending on the speed of their reactions.
But also, on how strongly you feel there *should* have been nobody on the other side of the door.
I realised this when I went for a 3am snack. I've always favoured cookies.
As I reached blindly into the jar I knew exactly what *should* be in there.
Not even once did I stop to think what *could* be in there.
I knew so strongly what *should* have filled the jar, that I raised it straight to my mouth an put it in.
Then I felt it move.
