When entering a conversation, don't interrupt to ask what the topic is.
Thirdly, politeness forbids us on entering a company to inform ourselves of what has been said in it. If, from ignorance of the subject, we cannot seize the thread of conversation, we should limit ourselves to seeking only a brief explanation, if we can do so without interrupting others; but if we foresee that the explanation may entail a wearisome or embarrassing repetition, let us be silent. Let us whose consecrated life should be a perpetual sacrifice wait till the occasion offers of informing ourselves without inconveniencing anyone. It is the duty of those assembled, or rather of the one that presides, in a few words to inform the newly arrived of the subject of conversation.
We do not love people so much for the good they have done us, as for the good we do them.
Love does not consist of gazing at each other, but in looking outward together in the same direction.
It is not a lack of love, but a lack of friendship that makes unhappy marriages.
