     ♦ "Да, в меня здесь все влюбляются", - с угрюмым самохвальством сказал Передонов. "Ну, вот видишь, вот ты и лови момент", - убеждал Рутилов (Сологуб 1). "Yes, they're all in love with me around here," said Peredonov with sullen boastfulness. "Well there you are, and you should take advantage of it," pressed Rutilov (1a).
