Most of the time I don't think we realize how watchful we are, how much energy is spent on vigilance. It's the small things that cue us in--the random headache, the tightness in our shoulders, our arms wrapped tightly around ourselves, a vague humming in our ears after a long day.
We never let our guard down because we refuse to remember that it's all unfolding as it should. We refuse to relinquish control; we refuse to have faith in something outside of ourselves. Sad, really, how isolated we become, and how much of that isolation is of our own doing.
