Errrr....uhh...Good Afternoon!

I can't remember if we greet each other with "Good morning," "Good afternoon," or "Good evening" in the States, but it's quite proper and common to greet each other here that way.

In between periods, walking through the hall to my office or to my next class, I often see old or current students. Because in their culture the difference between morning and afternoon is so ambiguous, it's difficult for them to know how to greet me.

A common passing goes something like this:

-Student notices me.
-Slight anxious/panick look on student's face as student lifts arm to check time while saying "Errrrr...uhhhh..." and eventually decides,"....Good MORNING!!" with a proud grin.

I repeat the greeting if they're correct, or greet them with the proper greeting. (Sometimes even after checking their watch, they still greet with "Good morning" at 3 in the afternoon...
