In class 2-3 (the 1990s) I brought the pyramid of Rubik (Mefert) to school and twisted it on the shifts. My classmate with the words “Oh! And I know how to collect such things,” she asked to twist. I was tired and I decided to let her torture. She turned aside and literally in 15-20 seconds on the palm stretched me the ready-made pyramid! My friends and I just broke up, because we could have collected something like a single barrel. They picked up and asked to repeat. 15-20 seconds and ready.
We then decided that there must be some secret to quickly gather it, because none of us did. Couldn’t we all be so stupid?
After the summer holidays, she did not return to her class. The teacher said that she was recognized as a wanderkind and sent to study in a cool high school. A good leader even showed us an article about her in the newspaper. It was also about the fact that "I've read all the textbooks already" she wasn't lying then either.)
