A few years ago I had some tests to screen for cancer, and I was nervous about the outcome. My anxiety was magnified as I thought about the fact that while the medical personnel were well-trained and extremely competent, they were also strangers who had no relationship with me.

After awakening from the anesthesia, however, I heard the beautiful sound of my wife’s voice: “It’s great, Honey. They didn’t find anything.” I looked up at her smiling face and was comforted. I needed the assurance of someone who loved me.
