This morning I came out of the subway and was walking toward my office. I am generally on the lookout for people moving more slowly so that I can move around them. Ahead of me I noticed a woman with her head down and her right arm bent up at the elbow, in the now-common posture of someone looking at a smartphone while walking.
I moved to my right, and as I came up behind her I saw that she was not looking at her phone, but in fact was deeply engaged with written material on an old-fashioned clipboard. I was pleasantly surprised and a little amused.
