Putting Feynman aside, this is how -all- teachers should be. I had maybe two in all my years of public school that came anywhere close. It's sad that teaching is not a highly paid and prestigious job. And it's a two way street, most of the teachers now are the same awful ones I had, latching on to statements like mine, yet demanding more money. It's a race to the bottom, and a detriment to our country.
In the county I live in you’ll actually make more as a door dasher than a public school substitute teacher.
