Perhaps you think it valuable?
It's nothing, sir; it's dross, it's dirt, compared to my wife's diamond pin! There's a jewel, if you like! It will be worth a fortune to us when we sell it.

A gift, dear sir! I'm afraid I've been too familiar with you.

Speaking as a born gentleman, I beg to present my respects, and I call you 'dear sir.' Did I tell you the diamond pin was a gift?
It's nothing of the sort; we are under no obligation; my wife, my admirable wife, has earned that diamond pin.

By registered post; and what I call a manly letter from Lord Harry.

He is deeply obliged (I give you the sense of it) by what my wife has done for him; ready money is scarce with my lord; he sends a family jewel, with his love.
