He was one of the most outstanding teachers that I had ever encountered. Most educators are there because of their willingness and eagerness to teach. That is who they are. Please allow the teachers to do their job. If parents would do their job, teachers would have it so much easier.
Biology is a science.
Home economics is not. Don't ever make assumptions that all teachers do things that are dangerous to students because of one irresponsible act from one teacher. There are hundreds, if not thousands, of exceptionally excellent teachers in this city. Reprimand the one, but don't berate the 99 percent of us that not only take great care of your children every day, but also manage to give them an excellent education in an overcrowded classroom. This includes their parents.
