The placing of your arms is a separate problem, interesting in its own right and, in a way, even more complicated, but of lesser importance, since no matter where you put them they will not normally come into physical contact with the Doctor. You may do anything you like with them (you wouldn't, clearly, put them on your knees in imitation of him). As a rule I move mine about a good bit, leaving them in one position for a while and then moving them to another. Arms folded, akimbo, or dangling; hands grasping the seat edges or thighs, or clasped behind the head or resting in the lap -- these (and their numerous degrees and variations) are all in their own ways satisfactory positions for the arms and hands, and if I shift from one to another, this shifting is really not so much a manifestation of embarrassment, or hasn't been since the first half-dozen interviews, as a recognition of the fact that when one is faced with such a multitude of desirable choices, no one choice seems satisfactory for very long by comparison with the aggregate desirability of all the rest, though compared to any one of the others it would not be found inferior.
It seems to me at just this moment (I am writing this at 7:55 in the evening of Tuesday, October 4, 1955, upstairs in the dormitory) that, should you choose to consider that final observation as a metaphor, it is the story of my life in a sentence -- to be precise, in the latter member of a double predicate nominative expression in the second independent clause of a rather intricate compound sentence. You see that I was in truth a grammar teacher.
