Doubt? ASK ME

LOMOV: I’ll show you the documents, Natalya Stepanovna!
 
NATALYA: No, you’re simply joking, or making fun of me. What a surprise! We’ve had the land for nearly three hundred years, and then we’re suddenly told that it isn’t ours! Ivan Vassilevitch, I can hardly believe my own ears. These Meadows aren’t worth much to me. They only come to five dessiatins, and are worth perhaps 300 roubles, but I can’t stand unfairness. Say what you will, I can’t stand unfairness.
 
LOMOV: Hear me out, I implore you! The peasants of your father’s grandfather, as I have already had the honour of explaining to you, used to bake bricks for my aunt’s grandmother. Now my aunt’s grandmother, wishing to make them a pleasant...
Explanation:
 
And Lomov was quite confident about his claim that he could even show the documents to Natalya, who insisted that Lomov was quite serious about his claim. Natalya disregarded Lomov's assertion and informed him that he was joking since she believed the Oxen Meadows had been their property for the previous 300 years and could not conceive of anyone claiming ownership of it at present. She informed Lomov that while the land was only five dessiatins, worth about 300 roubles, it wasn't about its value, and she couldn't stand Lomov's unfairness. One dessiatin is equivalent to 2.7 acres of land in Russian units.
 
Lomov pleaded with Natalya to at least pay attention to what he had to say. He continued by saying that the peasants of her great-grandfather used to bake bricks for his aunt's grandmother before Natalya cut him off.
