The Unforgotten Lesson of Mr. Pumble

Mr. Pumble, a meticulous test examiner, had been assigned to certify a crew of miners in a labyrinthine iron mine. Although he had memorized the official manuals, he still clutched a worn answer key like a talisman, convinced that it would protect him from professional embarrassment. The descent into the dimly lit shaft, which was accompanied by the rhythmic clatter of the mining cart, made his stomach churn. He reassured himself that the process was straightforward: ask the questions, check the answers, and stamp the certificates.

Tragedy struck when his leather bag, loosened by the jolting cart, tumbled into a deep drainage channel. The answer key, along with his glasses and a soggy sandwich, disappeared into the murky water. Without the key, Mr. Pumble felt as though his entire professional identity had been erased. He could not even recall the correct sequence of emergency shutdown procedures, which he had reviewed only the night before.
