Pope Francis recommends that families frequently use: May I? Thank you. Forgive me. These 3 phrases, he said, "open the path to living well in a family, living in peace."..."Sometimes it seems that we are becoming a civilization of bad manners and dirty words as if they were a sign of emancipation. We hear them so often, even publicly," he said. "Kindness and an ability to say 'thank you' are almost seen as a sign of weakness."
