DON'T MENTION IT.
"DON'T mention it again for your life."
"No, of course not. The least said about such things the better."
"Don't for the world. I have told you in perfect confidence, and you are the only one to whom I have breathed it. I wouldn't have it get out for any consideration."
"Give yourself no uneasiness. I shall not allude to the subject."
"I merely told you because I knew you were a friend, and would let it go no farther. But would you have thought it?"
"I certainly am very much surprised."
"So am I. But when things pass right before your eyes and ears, there is no gainsaying them."
"No. Seeing is said to be believing."
"Of course it is."
