I saw something interesting on American television this weekend. They were saying that, like the old phenomenon where young European girls would come to the U.S. to work as au pairs, taking care of children, it is just as common today in the U.S. to see grandmothers acting as au pairs, because grandmothers are very busy.
J'entendais à la télévision américaine, en fin de semaine, qu'autant on avait autrefois les jeunes filles au pair qui venaient d'Europe s'occuper des enfants, on a en ce moment aux États-Unis des grand-mères au pair, car les grand-mères sont occupées.
