It's two mothers who talk about their sons.
The first says:
- My son, he's a saint. He works hard, he does not smoke and for two years he has married, he has not looked at another woman.
The other answers him:
- Bravo! But my son is a real saint too. Not only has it been three years since he has looked at another woman, but moreover, he works on fixed hours, he always comes back on time for meals, he exercises every day, and he no longer drinks a single drop of alcohol.
- Oh, there, said the first women, As you must be proud.
- Oh yes! And when he gets his parole next month, I'll make him a big party to celebrate!
