empty head

I have empty-head-syndrome. It's sooooo empty in there it's not even funny.
Just one of those days. Although did start really good. I got enough sleep, got up in time, coffee was great this morning....nothing to complain about. But then I got off my nice VRE and had to use the Metro with its delays and PEOPLE. BUT.....I get to go home early today and that keeps me going.
I guess my head isn't that empty after all.
