Student bike

Military Department. Somewhere in 1996-97. Students from the SSU. phys-tech. and economy faculties.
 Lecture on military topography with filmstrip, the teacher reads the screen blankly. Student saving talking, not listening.
Prof sharply: "Fellow student, get up! I repeat what I said. "
Offbeat clueless, but here he tells a neighbor and he begins to blatantly read from the screen. Prof neponyatkah surprised, to say nothing.
"Sit down»
 The student starts talking again, his rousing, history repeats itself. Prof completely awesome. And for the third time all repeats. But this time the student quite relaxed and I started to read a paragraph NOT ONE. You had to see the happiness on the face of the teacher. "You, fellow student, did not hear talking!". Prof happy as an elephant.
 He did not understand.
 We just war died - they are always so tupili. What is the teacher attempts to solve the problem of the image of a filmstrip pevernutoy by inverting the screen.
Several times turned :-) We crawled.
