Andrei Belyaev, a student of grade 6 B, started his business with a stall in the yard, where he sold Pepsi-Cola on tap. Then he switched to miraculous ascorbic acid powders, offering them to classmates under the guise of a memory-improving medicine. And it burned out again. From the entire class there was only one buyer - Leshka Baibakov. There was also a mistake with sea salt, the production of which he established from iodine and ordinary salt, which his mother adds to the soup. At the very first pharmacy, he was advised with business-like straightforwardness to look for another market for his product. And this despite all the assurances of the excellent quality of the latter. An attempt to sell old toys was also unsuccessful. Mom was on the alert. As a result, the toy business was closed down before it even started. Money lived its own life, unknown to Andrey. Sometimes their paths did cross. Then there were several coins in his pocket. However, the money did not stay there for long, and therefore his pockets were mostly empty. Capricious fortune stubbornly refused to notice Andrei’s efforts, but fate, in the person of grandfather Adam, gave him another chance.
