I'm a Northern Girl
I had an office directly outside that of the Chairman of the Board once. He threw staplers. And once a telephone. The desktop kind, not a cell phone.
As a whiskey drinking non-recovering alcoholic, who spends many mornings green around the gills, I find that offensive.Most of the boards we had in the schools I attended were green, not black, so perhaps green board would work. My apologies to any green people made sick by the use of that term.
