Do viđenja means “goodbye” – the polite farewell you need when leaving a restaurant or a shop.
The story picks up directly from the bar in the last video: you have had your drink, thrown something into the tin and say goodbye. The landlord takes the tin, waves with it, dances a cha-cha-cha and waddles like a duck – tin, waving, cha-cha-cha and duck give you do viđenja.
Listen closely to how Ljubica pronounces the đ: it sits somewhere between an English “dj” and a soft “g”.
