выйти на след("I searched Marvis Bay like a bloodhound, but nobody came forward to claim the infant. (...) It wasn't till, by another inspiration, I thought to ask the sweet-stall man that I got on the track." (P.G. Wodehouse)ART Vancouver)
установить взаимопонимание(So it's a matter of listening to what your partner wants and responding to it and getting it on track. When it's on track, you know it's on track. – Когда такое взаимопонимание будет установлено, вы это почувствуете. ART Vancouver)
