言外之意之差別待遇The Differentiated Treatment for Hidden Meaning in One's Words

無利害關係之人，倘無言外之意，毋庸腦補；縱有言外之意，亦可風逝，以求耳空心清。蓋所言之意已無所謂，何況言外之意矣。

Facing a non-interested person, if he has no hidden meaning in his words, we shall not presume it; even if he has a hidden meaning in his words, we may also let it go, so that we can keep peace and quiet. In fact, even his word is not considerable, not to mention a hidden meaning in his word.
