Dobar dan. (Good day. My all-purpose, pass-you-in-the-street greeting.)
Zdravo. (Hi, though literally it means, Health.)
David learned a new greeting this week when he got in a taxi and a taxi driver said, "Imali umoran? (Are you tired?)"
David's Bosnian companion started laughing. "That's just one of those strange ways we in Bosnia greet each other."
So later, David tried it out on someone.
The polite answer, apparently, is, "Ne (no)."
