When I joined the foundation related to a small military school in Virginia, my boss, a retired U.S. Army colonel, made it clear. “If anyone wants to designate a gift, you say, ‘yes sir/ma’am and thank you.’’’ Not having been in the military myself, I thought this was a grand time to make a joke. “Well what if it’s for something silly, like basket weaving?” His look made it very clear, “Yes sir/ma’am and thank you” was the correct response.
