     ♦ Наутро разъехались все, кроме Руслана, который уже с неделю торчал на даче: то ли в отпуске, то ли взял работу домой, то ли заведение такое... что посещать не нужно, а денежки платят. Не разбери-поймешь... (Трифонов 6). The next morning they all departed except Ruslan, who had been hanging around the dacha for a week. Hard to tell whether he was on vacation, whether he had brought work home or whether...he could collect his pay without having to go in. Who knows? (6a).
