Never, never tell them. Try and remember that. Never tell anyone anything ever. Never tell anyone anything again.

Don't tell anybody I said that.

Don't tell me what I'm doing; I don't want to know.

Don’t tell me your name. If you don’t tell me your name, I can’t hurt your feelings by forgetting it.

Never tell all you know — not even to the person you know best.

Don't ever tell anybody anything. If you do, you start missing everybody.

Don't ever tell anybody anything. If you do, you start missing everybody

I can't tell you that. I'm not allowed to tell you that.

I couldn't tell her. I couldn't tell anyone. As long as I didn't say it aloud, it wasn't real.

Most secrets should never be told, but especially those that are more menacing to the listener than to the teller.

I can’t tell you just how wonderful she is. I don’t want you to know. I don’t want any one to know.

You don't want to know.

"Don't tell anybody anything. If you do, you start missing everybody."

- Holden Caulfield
The Catcher in the Rye

"You must not tell anyone," my mother said, "what I am about to tell you." (First line, "No Name Woman")
