Anton Chekhov's story "Home" is actually a story about a father's love for his son.
Here is the paragraph in which the father, lawyer Yevgeny Petrovitch Bykovsky tells his son that he has been disowned:
"Excuse me, Sergey Yevgenitch," answered the prosecutor, removing him from his knee. "Before kissing we must have a talk, and a serious talk . . . I am angry with you, and don't love you any more. I tell you, my boy, I don't love you, and you are no son of mine. . . ."
After reading the full story, you understand that the father was told that his son had been caught smoking tobacco taken from the father's office. Throughout the story, he is trying to find a way to explain to his son why he shouldn't smoke.
The full story makes it clear that Yevgeny has no desire to actually disown his child. Here is another quote from the story:
He looked at the boy's big dark eyes, and it seemed to him as though from those wide pupils there looked out at him his mother and his wife and everything that he had ever loved.
However, without knowing the full story, what can you infer from the paragraph about Yevgeny's anger?
First let's take a look at the wording. He starts off by saying "Excuse me," which is rather formal for a father talking to his son. It's a very calm introduction, showing that their conversation isn't an outburst of anger on the part of the father.
We then see that the boy had been sitting on his father's knee. This shows that before the chastising began, the two had embraced. Yevgeny clearly loves his son.
He then says: "before kissing," which implies that once the talk has finished and the boy has understood, they will be able to kiss after all.
All of these pieces of evidence show that the father is not actually disowning his child in an outburst of anger. Instead, he is trying to convey the severity of his lecture and make sure he has his son's full attention.
