touch

My mind wanders, sometimes. Most times. Yesterday, I thought about touch and how it is the only sense we have.

Smell, taste, sight, and hearing are all passive forms of touch. The receptors in our nose are touched by gas molecules, the buds on our tongues are touched by chemicals, the nerves in our eyes are touched by sunlight, and the hairs in our ears are touched by waving air.

And then there is touch, the kind that we shun and crave, the kind that lets us reach out and hurt or heal.
