When Charles deGaulle decided to retire from public life, the American ambassador and his wife threw a gala dinner party in his honor.
At the dinner table the Ambassadors wife was talking with Madame de Gaulle.
Your husband has been such a prominent public figure, such a presence on the French and International scene for so many years! How quiet retirement will seem in comparison. What are you most looking forward to in these retirement years?

A huge hush fell over the table. Everyone heard her answer
and no one knew what to say next.
Finally, Le Grand Charles leaned over to his wife and said, Ma cherie, I believe zee Americans pronounce zat word appiness.
