Just wondering, in countries besides the U.S.,
is nodding your head up/down a signal for 'yes?'
There's this person at work who, I think, is from
Germany. He asks me questions, and sometimes I
reply with a head nod. But yesterday I started
thinking, what if Gemans don't know what a head
nod means? The guy would probably think I'm a
looney...
So, is a head nod a universal signal for 'yes,'
or does it only apply to the United States?
