Pope advises couples to say please, thanks and sorry for happy marriage

Pope Francis has passed on some words of wisdom to couples for a successful marriage - say "please, thanks and sorry".

Francis told 25,000 lovebirds gathered in St. Peter's Square that showing courtesy, appreciation and repentance go a long way toward conserving and enhancing love over time, the New York Post reported.

He also asked the couples never to finish the day without making peace because if they end the day like that, what they have inside becomes hard and cold and it becomes harder to make peace the following day.

He added that the perfect family doesn't exist, nor the perfect husband nor wife.
