This is a very cozy Malyshkova book for boys from one year to 3 years. In it, the story of the relationship between parent and child is shown through a "machine" analogy: a truck and a trailer, which is nowhere without a truck. As the trailer wants to quickly rolls down the mountain, as pays attention to the chickens, as the truck is angry at the trailer, which unhooked (read "pulled his arm") and rolled away. But no matter how angry the older man is, he will always, always come back for his trailer...
