Answer:
He tries to reason with his son why smoking is a bad thing to do by threatening to disown him.
Explanation:
Yevgeny Petrovitch was a court prosecutor and single father of the seven-year old boy, Seryozgha in the book 'Home' by Anton Chekhov.
Yevgeny's house keeper (or Governess) had just informed him that she caught his son Seryozgha, smoking! She wanted Yevgeny to address the issue before it got out of hand.
In an attempt to solving the problem, Yevgeny expressed his anger and displeasure at what the young boy had done and threatened to disown him as his son. He did this reasoning that his son would grasp the enormity of what he had done.
The three reasons for which Yevgeny was angry with Seryozgha are:
1) that Seryozgha actually smoked at a young age.
2) That Seryozgha lied about the number of times he had smoked.
3) That Seryozgha stole by taking tobacco that belonged to Yevgeny from his table
