Read the following passage carefully and answer the questions that follow:
I’m thinking of having a go at the blackcock, honoured Natalya Stepanovna, after the harvest. Oh, have you heard? Just think, what a misfortune I’ve had! My dog Guess, who you know, has gone lame. He is old, but I wouldn’t take five Squeezers for him. Why, how can you? Guess is a dog; as for Squeezer, well, it’s too funny to argue. Anybody you like has a dog as good as Squeezer.

Natalya:No, it was you!

Chubukov:I tell you it’s not my fault. [Lomov appears at the door] Now you talk to him yourself.
