Time on (one's) hands is defined as a period that is not already designated for some activity or use.
I am thinking about waiting.
Long before the magic carpet ride resided in our pocket, eyes met, contacts made, glances shared. Those secret smiles of common interest were commonplace. Those side eye leers of knowing and judgment became a language of waiting. Our minds free to consider the landscape. Time on our hands. Time to look upon the world. Up. On. And see our humanity reflected in the eyes of others.
