What was strange and very surprising and especially confusing was that in the first lesson (eighth grade) the students were noisier than usual, while the second lesson, where I assumed that the students would be noisy, the students were completely silent. They almost didn't talk to each other all the time (unless they were invited to do so) and they worked and counted all the time.
