"It is a circumstance which Darcy could not wish to be generally known, because if it were to get round to the lady's family, it would be an unpleasant thing."

"You may depend upon my not mentioning it."

What he told me was merely this: that he congratulated himself on having lately saved a friend from the inconveniences of a most imprudent marriage, but without mentioning names or any other particulars, and I only suspected it to be Bingley from believing him the kind of young man to get into a scrape of that sort, and from knowing them to have been together the whole of last summer."

"Did Mr. Darcy give you reasons for this interference?"

"I understood that there were some very strong objections against the lady."
