Getting up early makes me stupid

This getting up at 6 a.m. has strong negative influence on me. I found out that my intellectual abilities decrease by 50% at least on Mondays. Too bad because it is my intellectually most demanding day. I have two examples to document it.

(1) Dialogue with Marťa (who also got up at 6 a.m.)
Me: What?
Marťa: What?
Me: What “what”?
Marťa: What „what what“?
Both having the WTF expression on our faces.

(2) Me, Marťa and Jana ... while studying economics we started to discuss different alphabets used in post–Soviet countries and we wrote down the names of Azerbaijan (AZƏRBAYCAN or something like that. I am not yet an expert on this country) and Tajikistan (ТОҶИКИСТОН).
Jana: Write also Armenia.
Me: АРМЕНИЯ
Jana: Well, I meant in Armenian letters of course.
Me: Oops, error.
After some time thinking, puzzled.... I don’t know some of the letters.
Checking some Armenian coins....
Me: I know why. It is called Hayastan in Armenian, I was trying to write Armenia. So now I know how to write it: ՀԱՅԱՍՏԱՆ
How could I forget something like that!
