What do chameleon and fat and thin stories have in common?

The events of the stories take place in quite crowded places: in the market square and at the train station. The theme and problem of these Chekhovian stories are the same. These are humorous stories about the relationship between people of different classes. We see how people who are lower in their social status in society are forced, in order to protect themselves from the disfavor of the higher ranks, to curry favor, fawn, to please, to try to make decisions not according to the law, but to please the higher ranks. Each of the stories provokes indignation, indignation.
