http://www.washingtonpost.com/lifes...0657d0-8a98-11e3-833c-33098f9e5267_story.html DEAR MISS MANNERS: I am a businessman who frequently flies both domestically and internationally. I also happen to be an insulin-dependent diabetic. I currently do my glucose testing in my seat. It does involve using a lancet device to get a drop of blood to test, but is fairly unobtrusive. Of course, all lancets, alcohol preps and test strips are stored in my test kit for proper disposal later. Am I being rude to perform this test next to a stranger? Injections I perform privately in the plane’s lavatory. In the airport, I use the counter by the wash basin, since most water closets have no room for insulin vials and other supplies. Many people seem to stare and resent the fact of performing such a function in this space. I have also had children ask, “What is that man doing? Isn’t that a bad thing?” (They’re obviously thinking of their drug education classes.) Am I too self-conscious? GENTLE READER: Absent an emergency, medical applications (like bodily functions and grooming) are properly done out of sight — meaning in private or in a restroom — unless they can be done so surreptitiously as to be unrecognizable as such. Miss Manners does not object to a pill taken at dinner, so long as it is not accompanied by a dissertation on your cholesterol. The technology associated with diabetes is fast approaching this standard, although Miss Manners draws the line at drawing blood. Restrooms exist to provide a proper location for such necessary activities when away from home, and those who use them have no business monitoring the respectable, if sometimes unaesthetic, activities of others. You may chose to tell children that it is a medical procedure, or ignore them and let their parents do that. Miss Manners would hope that any parents present would also resolve to teach their children to be more discreet with their curiosity.
