The other day, John and I were walking — it's our form of exercise. I was in the middle of telling a story and he interrupted with an urgent and loud mouth noise. The sound was so alarming that I thought an emergency situation was unfolding, but I couldn't see anything out of the ordinary. He needed to tell me, at that exact moment in time, that while he was driving home that evening, he had stopped at a light. He looked over and saw the most amazing scene. He saw a woman signing to a blind man.
