When responding to any adult, you must answer by saying “Yes ma’am” or “No, sir.” Just nodding your head is not acceptable.
Because I grew up in rural North Carolina, this rule comes    36   to me, and it seems the obvious choice to come first. If you want children to respect you, you have to let them know    37 . Simply telling them you want them to address you by saying “sir” lets them know   38     you expect them to treat you. I also tell my students it’s a very useful tool when    39  with adults, and furthermore it also     40   handy for any adult interacting with another adult. Case in point: I was   41    the phone recently with the phone company discussing the inaccuracies(差错) of my    42  . The lady I spoke to was not 43   and seemed annoyed.    44  , in the midst of the conversation, I threw in a “yes, ma’am,” and her entire  45  changed. She became far more helpful and   46  to deal with, and she   47  cutting my bill in half.
Some of my students in Harlem were to be   48  for a chance to attend a high-rated junior high school. The school only had thirty openings for the following year, and twelve of my students were   49  the many kids across the city who applied for the spots. I practiced what the interview would be   50  with my students, and one main thing I stressed was, “  51  you say ‘yes ma’am’ or ‘no sir’ no matter what!” Weeks after the interviews, I was delighted to hear that all twelve of my students had been   52  . When I talked with the admissions director at the school, the main   53  he made over and over was how   54   my students were in their interviews. It seemed like just such a simple thing to do, but it gets   55  .
