Never ask a man if he is from Sparta: If he were, he would have let you know such an important fact - and if he were not, you could hurt his feelings.

Anna Petrovna: Never talk to women about your own good qualities. Let them find out for themselves.

Sometimes, when you don't ask questions, it's not because you are afraid that someone will lie to your face. It's because you're afraid they'll tell you the truth.

All well bred persons lie – Besides, you are a woman; you must never speak what you think…

One should never trust a woman who tells one her real age. A woman who would tell one that would tell one anything.

I lay it down as a general rule, Harriet, that if a woman doubts as to whether she should accept a man or not, she certainly ought to refuse him.

Questioning is not the mode of conversation among gentlemen. It is assuming a superiority, and it is particularly wrong to question a man concerning himself. There may be parts of his former life he may not wish to be made known to other persons, or even brought to his own recollection.

Never ask people. Not about your work. Don't you know what you want? How can you stand it, not to know?

You should never say anything to a woman that even remotely suggests you think she's pregnant unless you can see an actual baby emerging from her at that moment.

Do not expect people to tell you the truth because they also lie to themselves.

Never say anything about someone that you wouldn’t say to them directly and don’t try people without accusing them to their faces.

Never say anything about yourself you do not want to come true.

Never try to impress a woman, because if you do she'll expect you to keep up the standard for the rest of your life.

Never lie in bed at night asking yourself questions you can't answer.
