Why does Monsieur Durand tell a lie about his birthplace?
Monsieur Durand tells a lie about his birthplace because of two different reasons:-
He fell in love with a woman before his age. He wanted to marry that lady. So he left his birthplace and moved to Switzerland. To save his and his wife’s reputation, he tells a lie.
He fought against his own motherland France from the side of Switzerland. To hide this shame, he tells a lie.
