The Heisenburg Uncertainty Principle states that you can’t measure both the position and velocity of an electron at the same time. The implications are that the electron exists as either a particle or wave depending on how you look at it and can even be said to not exist until you decide to look for it.

Happiness has a strange uncertainty. A warmth growing in the back of the belly, in the way the faces of others and the previously dark corners begin to glow. Before I looked, were they glowing?

When I begin to look too hard, the magic fades. Question too hard and I see the dust again.

Perhaps happiness is a question of velocity and not of position. A sense of movement. Of connection. Of togetherness. Of purpose. Try to measure exactly where you are at the same time and you loose the sense of motion that was carrying you along so nicely.
