I generally try to avoid publishing images of people in any pose or situation that would be a source of even modest embarrassment, although sometimes I might compromise that idea a bit for large groups where one person away from the main subject is slightly “compromised.”   To demonstrate where I draw that line, you should know that I wavered for several weeks over whether to publish this image.  I have gone ahead with it, obviously, but rest assured, anything more embarrassing than a wide open mouthed yawn will probably never see the light of day.
