I arrived early one morning for my weekly visit to the chiropractor so I just waited and sat in my car drinking a cup of coffee. A short distance away I noticed two women on a bench engaged in a conversation. I could not hear them speak but it was fascinating to notice their body language as they were engaged in a dialogue.
The movements of their heads, hands and shoulders communicated the sense of a language. They were too far away to see the movement of their mouths. I could tell when a sentence was completed by the abrupt motions of their heads and hands. They gave the impression of saying something very important yet I could hear nothing.
Just the gestures of one of them seemed to intimidate the other one. It was almost like a silent drama unfolding but they may have just been talking about the weather.
