albanian habits

In Albania people nod in an opposite way: if they want to say 'Yes' Albanians move their heads from right to left, if they want to say 'No' they move them up and down. So when I was in Elbasan I asked a local inhabitant if there were any buses to Tirana and he nodded 'No' in his way. So I replied: 'Good. And where can I catch one?' and he continued to nod the same way. I almost got angry with him and only later I could grasp the misunderstanding.
