"Yes" and "No" in Bulgarian

The players get into a circle. The leader is in the center. He/she speaks to the players: " You know that many gestures are international, for example, some gestures of threat. But there are some differences in the sense of one and the same gestures in different countries. So, Russian people shake their heads in token of negation. But the Bulgarian, on the contrary, shake their heads in token of consent, while they nod their heads in token of negation. Now I want to ask you some questions in Russian, but you must answer them in Bulgarian". You may ask the following questions: Have you had dinner today? Do you like to dance? Do you know the name of the person next to you?
