In most countries, a nod signifies agreement and confirmation. This is a smoothed form of bow - the person bows symbolically, but immediately stops, resulting in a nod. Bowing is a gesture of submission and submission. A nod indicates that we agree with the other person's point of view. Studies have shown that people born deaf-blind and dumb also nod in agreement, which indicates the innate nature of this gesture. But for some peoples, the opposite is true ...
The most famous and strange trait of Bulgarians is that when they disagree with you, they nod their heads up and down, and when they agree left and right. It's almost impossible to get used to it, because the rest of the world uses these gestures the way we are used to. In places where tourists gather, local residents, of course, remember that this national peculiarity needs to be controlled. The situation is worse in the regions, where the tourist's foot rarely steps, there is a complete feeling that the locals are simply making fun of you. The funny thing is that even those Bulgarians who try to nod their heads like the rest of the world do it in an unusually comical way. If they agree, they nod their heads obliquely (diagonally), for example, you move your head from the left corner of the monitor to the right and vice versa.
At the same time, the Bulgarians themselves do not know the reasons for this national peculiarity. According to one of the versions (the most plausible), the tradition goes back to the times of the Bulgarian-Turkish warriors. The Turks tortured the Bulgarians, holding a knife to their throats, asking: "Do you renounce the Orthodox faith?" If the residents answered negatively (shook their heads left and right), the Turks executed the refuseniks. It was then that the Bulgarians agreed to swap their gestures among themselves: an affirmative gesture with the head - left and right, negative - up and down. Experienced guides recommend tourists not to pay attention to the nods and gestures of local residents, focusing their attention on words, so “yes” means “yes” in Bulgarian, “no” means “no”.
And one more thing: if you ask the locals for directions, this time you should not pay attention to the words, you should look where they point with their hand. Many times Russian-speaking compatriots cursed them for nothing, dodging in circles around all the neighborhoods. And the thing is that "to the right" in Bulgarian means "straight" in Russian.
