Culture Shock #52: Germans don't know when noon is

Here's a funny thing I found out recently. Germans think "noon" is a quick and quirky way to say "afternoon". In other words, they don't understand that "noon" refers to a specific time in the day. Here's an example of a conversation I've had multiple times with a variety of Germans:

Me: Great! Wanna meet at noon?

German: Sure! When?

Me:...noon?

German: Yes, but when at noon?

Me: ....how about...at...NOON????? 

(For all the Germans reading this post, "noon" is 12 o'clock in the daytime. Please just learn that. It'll make my life easier.)
