“Dès qu'ils furent seuls, M. Lheureux se mit, en termes assez nets, à féliciter Emma sur la succession, puis à causer de choses indifférentes, des espaliers, de la récolte et de sa santé à lui, qui allait toujours couci-couci, entre le zist et le zest.” — As soon as they were alone, Monsieur Lheureux in sufficiently clear terms began to congratulate Emma on the inheritance, then to talk of indifferent matters, of the espaliers, of the harvest, and of his own health, which was always so-so, always having ups and downs.
