The story is inspired by Kir Bulychev's cycle about Alisa Selezneva. I was waiting for the excursion to Mars for the whole 10 b. Someone just wanted to skip class, someone was eager to collect a bunch of information for a report, and someone decided to wander through the Martian market stalls. But Asya Koroleva got into trouble as soon as the bus landed. Martian scabies, of course, is not fatal, but it is unpleasant. And it was this unfortunate allergy that triggered a series of events, from which both Asya and Pasha, upon arriving home, would receive a good reprimand from their parents.
