My last math course was 10th-grade geometry. I did well in it. I am still angry at the high school advisor who told me I didn’t need to take any more math or science classes because I was going to be an elementary school teacher. I am still angry at myself for going along with it.
The teacher of this course was a gentle human. He was slight and sported a handlebar mustache. I think that other kids in class made fun of him but I never did. Maybe he saw that I was on his side. He also had been a student of Bill Jordan, the father of my best friend throughout middle and high school.
