The true definition of "savoir faire"

Three French gentleman are discussing the true definition of "savoir faire"

"Mes amis, let me tell you the meaning of 'savoir faire': a husband comes home early, walks into the bedroom and discovers his wife in bed with another man - Pierre - in the middle of ze act. He does not react, but with great dignity walks out of the room and closes the door. THAT, mes amis, is 'savoir faire'!"

"Non non non!" says the second, "that is NOT 'savoir faire'! It is when the husband comes home, discovers his wife in bed with this Pierre. He first says with great politeness and perhaps a small bow, *'please, continue'*. Only THEN he walks out with dignity and closes the door. THIS is 'savoir faire'"

The third friend replies, "Mes amis you do not understand these things. It is when Pierre is in bed with his mistress, making love. Her husband comes home early and walks in ze door. The husband bows politely then walks out with great dignity and closes ze door, saying *'please, continue'*....

and Pierre *can*.
