convention many years ago. Since multicolored highlighters were a bit pricy at the time (especially to pass out to 100 techs), Jorge passed out small packs of crayons for each tech to highlight the sample schematics in their printed training handouts. Most of the class were OK with the idea of grownups using crayons and followed along like good sports. But I do recall one older tech whose pride was bigger than his ability to learn. He cussed and walked out saying he'd never May 2020 resort to "playing with kid's crayons" to fix a car. As a vocational school instructor, I think I must have had that man's son in one of my classes several years later. After several minutes of logical explanations on why the classroom exercise made sense, the young vocational student still refused to participate . . . so I failed him for that day's assignment. As a general rule, anytime we let pride get in the way of a promising new technique, we fail too. 5 MACS Service Reports
