When is honesty not the best policy?

I think honesty is not the best policy when you are caught doing something you have no business doing. You should not be honest if you are caught with another person other then your spouse. Should not be honest if did something illegal that could put you in jail. Honesty is not the best policy when you get in trouble in general if you are a good liar and anybody can believe your lies. But not being honest can always come back to you because you would not like it if somebody lied to you but if you are sure about lieng then oyu can lie about anything.
