"It is rude to look people in the eye" changed into "in the U.S. military you must not look the instructor in the eye," and finally into "look people in the eye when you talk,"…
The memory that “Looking into people’s eyes is rude” changed into “In the U.S. military you must not look into your instructor’s eyes,” and ultimately changed into “Look people in the eye when you speak.” Alternatively, I have two contradictory memories: one where side-glancing and looking from the corner of your eye are bad for your body and therefore must not be used, and the reverse where eye-ball exercises were recommended. Also, there is a proverb? idiom? that there are X people in the world who resemble you, but in the previous world it was that there are seven, whereas in the current world it has been reduced to three. Also, “When a man goes out, he has ten enemies” has been reduced to seven enemies. Alternatively, there is the observation that you no longer even see ill-at-ease-vibe delinquents or ruffians in the first place.
