How did Tschubukov react when Lomov told him that he had come to propose to his daughter, Natalya?

The Marriage Proposal by Anton Chekov is an instance of farce pointed towards the hypocrisy of Russian aristocracy. When Lomov first visits him, Tschubukov thinks that he had come to ask for money and he prepares himself to send him out of the house. However, on knowing Lomov’s actual intention, Tschubukov jumps with joy, embraces and kisses him and announces to his neighbors that he greatly loved and admired Lomov and says, “My dear fellow…I’m so glad to see you!” Knowing that the daughter would never give her consent to this marriage, the father plays a trick with Lomov and gives his daughter’s words to him. He even went to the extent of telling his daughter that Lomov was “lovesick”. Later, on realizing that his daughter would never agree to this relationship, Lomov becomes hysterical and shouts, “I’ll cut my throat! I’ll cut my throat!”
