        LONGPARA(Locale.US, "During dinner, Mr. Bennet scarcely spoke at all; but when the servants were withdrawn, he thought it time to have some conversation with his guest, and therefore started a subject in which he expected him to shine, by observing that he seemed very fortunate in his patroness. Lady Catherine de Bourgh's attention to his wishes, and consideration for his comfort, appeared very remarkable. Mr. Bennet could not have chosen better. Mr. Collins was eloquent in her praise. The subject elevated him to more than usual solemnity of manner, and with a most important aspect he protested that \"he had never in his life witnessed such behaviour in a person of rank--such affability and condescension, as he had himself experienced from Lady Catherine. She had been graciously pleased to approve of both of the discourses which he had already had the honour of preaching before her. She had also asked him twice to dine at Rosings, and had sent for him only the Saturday before, to make up her pool of quadrille in the evening. Lady Catherine was reckoned proud by many people he knew, but _he_ had never seen anything but affability in her. She had always spoken to him as she would to any other gentleman; she made not the smallest objection to his joining in the society of the neighbourhood nor to his leaving the parish occasionally for a week or two, to visit his relations. She had even condescended to advise him to marry as soon as he could, provided he chose with discretion; and had once paid him a visit in his humble parsonage, where she had perfectly approved all the alterations he had been making, and had even vouchsafed to suggest some herself--some shelves in the closet up stairs.\""),

Draußen auf den Feldern und den hohen Bergen lag der Schnee und Peter wäre in seinem dünnen Leinwandjäckchen bald erfroren. Es war also seine einzige Freude, hinaus vor die Hütte zu treten und den Sperlingen Brotkrümchen zu streuen, was er sich jedesmal an seinem Frühstück absparte. Wenn nun die Vögel so lustig zwitscherten und um ihn herumflogen, da klopfte ihm das Herz vor Lust, und oft gab er ihnen sein ganzes Stück Schwarzbrot, ohne daran zu denken, daß er dafür alsdann selbst hungern müsse."),
