"Why do you think it's a joke?"
"It is obvious. You think I am only tolerable. You will never propose to me, let alone fall in love with me. That was hilarious! Totally unexpected."
"Aaahhhh... I may have a sense of humour after all."
Darcy played along to save face.
"Who knew? And no one proposes like that! Imagine insulting your beloved and her family! Who would do such a thing?"
"You can say it's part of the ruse."
"Very clever. I do love surprises."
"Glad you were entertained. Have a good day, Miss Bennet."
"Till next time!"
