From the Literary Forum:

I am angry with everything today, most of all, the subject of OBJ. The model is this:
First-second-third class: "Children, the road must be switched to the green light..."
Fifth class: "Students, if you hear the evacuation signal..."
8th Class: Young citizens of Russia! Anti-gases are three standard sizes, calculated from the radius of the head.
Tenth class: "Students, if you hear the evacuation signal..."
11th grade: "Children, the road must be moved to the green light..."
It seems that the peak of development we have already passed...
