I give his name: Mr. Lewis was my Algebra I teacher. I was a freshman and sluffed off on my homework and so did not get the grades I wanted. I kept hoping, over the summer, that I would get him for geometry, and I did. I took an empty notebook and sat myself right in front of his desk. Entered every axiom, postulate and theorem. Did my homework religiously, whipped through my notebook and came out an A/B student. Great teacher.
And here I was teaching math skills to soldiers. Whodaguessed.
