I get out of my car walk through the cold and get into the lobby. And I'm still cold.
I write it off to "Hey I was just out in 18 degree weather"
I get into the elevator. And I'm still cold. I write this off to "Hey they probably have the dock doors open downstairs and cold air is coming into the elevator shafts."
I get to my office. And I'm still cold. I've got nothing to write this off to.
I open my email and read "Building management is aware of the lack of heat on the third floor"
That made me feel better!
