♦ Есть такие молодцы, что весь век живут на чужой счёт, наберут, нахватают справа, слева, да и в ус не дуют! Как они могут покойно уснуть, как обедают - непонятно! (Гончаров 1). There were, of course, those clever fellows who lived their entire lives at other people's expense, grabbing right and left, never giving a damn! How could they sleep in peace? How could they enjoy their dinner? Incomprehensible! (1b).
