"We were unquiet about your health, my son," said Catherine.
"You were wrong, madame; I have never been better."
"And to what happy influence do you owe this amelioration, my son?"
"To having laughed much, madame."
Every one looked astonished.
"Laughed! you can laugh much, my son; then you are very happy?"
"It is true, madame."
"And about what were you so much amused?"
"I must tell you, mother, that yesterday I went to Vincennes."
"I knew it."
