The very first day I had home-ec, the teacher asked if anyone knew how to make Macaroni & cheese. A lot of us raised our hands, and then she said, "Without the box" and I was the only one with my hand still up. She asked, "so how do you do it?" I answered, "first you make a white sauce..." and the teacher was so shocked that I knew how to make a white sauce that I already had an A by the end of the day.
