Back when I was 17 I worked in a factory somewhere in Scandinavia, extremely monotonous, but it was good pay and I sort of enjoyed it and I got pretty goddamn good at it too.

Anyway, there were always 2-3 machine engineers patrolling around fixing whatever problems arose etc., but this one particular engineer was always watching me work, and every time my shift started, he would come over and tune the machine specifically to match my speed. You could do it yourself, but finding a balance was pretty difficult as you would either make it too slow and produce less, or too fast so you got more material than could be processed, so you'd also produce less. With precise tuning, he basically managed to give me and the machine 100% productivity, no spillage, overlap or space between materials. It was a loud environment with hearing protection, so he never spoke a word to me, but I think he was Australian, so he was far from home. His last name was something along the lines of "Redwood" or something. I always wonder what he's doing now even though I never actually spoke to him.
