Shaking your head up and down to signify “yes” (Bulgaria)
This one is probably going to throw you off a bit. While visiting Bulgaria, it would behoove you to remember that yes means no and no means yes…at least to outsiders. What do we mean? Well let’s just say if your host asks you whether you enjoyed their meal, you had better shake your head from left to right, meaning yes. Shake your head up and down and you may well find yourself eating out for the rest of your trip.
