Elizabeth was distressed. She felt that she had no business at Pemberley, and was obliged to assume a disinclination for seeing it. She must own that she was tired of great houses; after going over so many, she really had no pleasure in fine carpets or satin curtains…The possibility of meeting Mr. Darcy, while viewing the place, instantly occurred. It would be dreadful!

– Jane Austen
