I teach French in a boys school. Sometimes this can be a very daunting job. My best teaching day was in my first year of teaching when one of my boys who struggled historically in French took a risk to participate. The look on his face when he realized that he was capable of communicating in this language, that until then seemed totally inaccessible to him, was priceless. Every so often it happens again, but nothing has been quite as joyful as that first moment of clarity and success.
