Oh my, Sir (a.k.a. The persistent gentleman).

Oh, hello, Sir. How do you do? What a beautiful day indeed. Your message? Oh, yes, Sir. I did receive them. I confess myself flattered by your invitation to supper. And tea. And lunch with your sister. And I am extremely fond of picnics! 

I do not find your constant missives a bother in the least. But of course you are galant, Sir! You flatter me with the excitement of a caged monkey. But I must be sincere and I must dissuade you. 

I am simply no good. I abhor sisters, I chew too loudly, I drink only water, and the sun leaves me without manners. You do understand. Don’t you, Sir?
