You learned quickly in Mr. M.'s high school algebra class that "Yes," not "Yeah," was the proper affirmative response to a yes-or-no question. Even when Mr. M. sat in the back of the room as a student teacher led the class, "Yeah" was still prohibited. When a student said, "Yeah," to the student teacher, Mr. M. reacted as if he'd just heard profanity. His voice boomed from the back of the room, "What was that?!" "I mean, Yes," the student corrected himself.
Mr. M. explained that he didn't even allow his own kids to say, "Yeah," to him, and "in this class, you are all my children!"
