I am the son of teachers, the husband of a teacher and friend to many who teach. It takes something special to be a teacher, ever more to be a good teacher, but to be an exceptional teacher takes love.
Modern schools deal with a mountain of challenges. Teachers must handle disruptive students who have little or no respect for rules or consequences, parents who leave the parenting up to the schools, and in many cases administrators who simply don't support the teachers. However, what occurs in this video is without question unacceptable.
