Describe Flora's conversation with Reuben about Cold Comfort Farm; do you think Flora is sincere?

Reuben enters the eating area, and Flora offers him some tea. He eyes her with hostility, believing she plans to claim the farm, but finally relents and has some tea. Reuben is silent for a very long time but finally mentions how he "scranleted two hundred furrows". As she struggles in a difficult conversation with Reuben, Flora realizes he believes she has designs on the farm. She does her best to assure him she has no desire to own a farm. Reuben leaves in frosty silence. But Flora believes the next time they have such a conversation, Reuben will believe her. She seems quite sincere as she has shown no interest in farming; the only interest she has shown in her life there is interest in the Starkadders themselves.
