As you may know, people stand on soapboxes in Boston Common, where freedom of speech and freedom of association are the rule. I had gotten off the Green Line of the MBTA, and ,when I was above ground from the subway tunnel, I saw a pipe smoker on a soap box. He had a megaphone in one hand and a calabash meer in the other. "If it weren't for tobacco," he said, "there wouldn't be pipes. And", he added, "if there weren't any pipes we'd all be smoking cigarettes and cigars." This observation got a round of appreciative applause. I clapped. I could see his point. I sat on an empty bench and pulled my pipe out of my pocket. I packed it and lit it. I enjoyed it. Everyone walking by seemed to enjoy it, too.
