This story was told to me by my mother. Her colleague from work has a son who goes to school, he is 9 years old. I have been missing more and more recently. Then the head hurts, then the throat, then the ass... and one day he approaches his mother and says, “I have, so and so... my urine is blue.” Naturally, my mother initially did not believe in this magic of transformation, but after convincing herself of this fact, she almost settled. And when your own investigation on the topic "what did you eat, drink? No matter what, I called the doctors home. The doctors, in turn, also divided their hands: "blue urine and no other symptoms, went to the hospital." And then the boy suddenly shaded and the mystery of the blue fluid was uncovered...In short, when he became less and less believed about the fictional symptoms, he realized that it was time to reinforce the magnificent acting skills with real symptoms, he remembered that if you eat a crayon from a pencil, the temperature will rise. The first person to be caught was a chemical pencil from the architect’s grandmother’s arsenal. The temperature did not rise, but the desired effect was achieved. Not without costs, of course.

At the fourth decade, you understand that to questions such as "and you know how to melt a bath / roast a stove / drive a car", in general, to do any banal shit is better to answer "no", adding "and I generally fuck how it is done."

Flexible prices are understandable. But why do they always bend up?

All the mess in our state is because of those quiet craftsmen, by the efforts of whose madness of instructions is transformed into something working.
I once worked as a freezer at a repair site of a large factory. There was a competent freezer-takar-grasshopper in one person. He told how in the times of the USSR he travelled, as part of the participants of the social competition of workers, to the GDR. There the Soviet Union built a factory for the German brothers.
There was a lot of experience with Soviet workers. The notion of "my instrument" or my machine was absent (unthinkable for the USSR). Every machine is clean, dirty, ready to work. Near the closet with the tool - there is everything that is provided by the technological map (heat - drawings were delivered to the workshop with technological maps). On the door of the toolbox, the tool layout scheme - everything is in place. Workers are not engaged in the adjustment and cleaning of the machine - there are slugs and cleaners for this... Well, this is a lyric.
There is a work shift. The time is right, the spark is spread - the signal of the start of the lunch break. The German tower shakes the palm on the "fungus" stop... Directly during the passage... Just like STOP without taking the cutter. The spindle slows down, the cutter hits the part, breaking the solid alloy plate, everything with the crack stops. The Germans are always in the dining room. It goes back and begins: throwing the damaged work in the cube with marriage, replacing the cutting machine, adjusting, installing a new work... On the direct question - "why did he do so?" The German replied simply, “That’s what is written in the instructions. If I do it to a friend, I will hurt him. My actions will hide the error of management.” The process of clarifying system errors is not so fast..In the process of trials, the taper continued to dig the tool and parts. The conclusion of the trial: A specialist who allowed working instructions without technical analysis was punished (they were simply translated from Russian). We changed the instructions, where it was prescribed that the worker must first remove the cutting machine; to make sure that the machine stop is safe and will not damage the equipment or part; or to finish the cutting machine passage - and only then to defuse the machine.
The result: several days of marriage, the real culprit is identified (not the employee - but the one who gave the wrong instruction), the instruction is corrected. Thus e. The problems are solved systematically, and not by the mind of a simple worker or worker. This is the real responsibility of the leaders.
P.S
I took the story from the comments, the source indicated twice - https://www.anekdot.ru/id/980636/#c1177489

A group of mathematicians caught an esoteric who claimed that all knowledge originated in humans, and forced him to meditate until he learned to solve differential equations.
