On one of the non-profile subjects at the first lecture, I remember, an elderly faint preacher ran into the house and immediately said: "I can tell you in two ways: either I will hate you, or you will hate me. What do you choose?"
The group was in a deep stupor. Prepod struck us and left! But, judging by the fact that neither the subsequent lectures nor the accounts of problems arose at all, the teaching of us mentally burned in all the boilers of hell.
