I currently teach management courses at a local university, including Introduction to American Business and Culture to incoming international graduate students.
During high school, as a student worker with a local Federal agency, I tried to impress the secretary by saying, "I want to 'reinerate'...". Ms. Yamada promptly corrected my pronunciation, gave me the dictionary, and instructed me to look up the word. I looked up the word, copied its definition, and added it to my "new word" listing.
