I liked it when they taught the subjects and left out personal opinion. If I had a child today in school and a teacher took a little extra effort explaining how to do a math problem or something the child didn't quite understand, I would encourage the child to thank the teacher. I'm now 76 years old and a teacher took extra time with me explaining how to do math problems and I've never forgotten him. I failed to thank him and have regretted it all these years. If I could find his daughter I would thank her...
