About 10 years back, I had to take a mandatory certification at the forestry school.
I noticed that one of the old teachers up there, whom I've known for 30+ years was limping badly and sorta staying away from everyone, not meeting anyones eyes.He kinda looked like a dog, that someone had thrown cold water on.
I asked someone else, what was up and was told that after 30 years of teaching chainsaw safety classes, he had cut a small tree down in his yard while not wearing PPE and cut his leg badly.
Can you imagine how stupid and ashamed he must have felt.
