Living together is an art, a patient, beautiful, fascinating journey.
It does not end once you have won each other's love. Rather, it is precisely there where it begins.
This journey of every day has a few rules that can be summed up in three phrases which you already said, phrases which I have already repeated many times to families, and which you have already learned to use among yourselves: May I - that is, "can I", you said thank you, and I'm sorry.
(Pope Francis)
