Today is Self-Government Day. You are in the 10th grade and today you are going to teach a literature lesson to the 8th grade. There were two unusual boys in the 8th grade. One of them had red hair and strange yellow eyes, always such a lazy hooligan, and his opposite, with white hair and pure blue eyes, a kind, late boy. You sometimes saw them during breaks, the first one running along the corridors, and the second one silently reading. But right now you are heading to their class.
