As I’ve mentioned before, sketching people in waiting rooms is fraught with hazards. One is the prospect that the person you select as a subject will become aware, and protest being drawn. Another is that the person you are drawing will get up and leave before you finish. This is what happened in the sketch below. I was leisurely leading the pen point from the shoe, around the legs and up the arm. At about the shoulder, the young man got up and left. I feverishly sketched in his head as he was moving away. Memory replaced my visual input to allow me to scribble the end of the portrayal.
