You Might be a Coppersmith if

if you are green around the gills.

... if you know that the patina of copper is called verdigris.

The green patina is.  The red one is not.

If you feal a tear slowly roll down your cheek as you glance up looking for the first glint of green on the cupola that you fabricated and installed 15 years ago which at last glance had turned dark Brown, only to see that the buildings owner has had it polished to a new penny shine. 

Back in the '50s a geology professor at the University of Wyoming built a full size T. Rex out of copper plates which still stands besides the entrance to the UW Geology Museum.  The expectation was that it would turn green as it weathered.  However, there is not enough reactive chemicals in the rain in Wyoming to create verdigris (copper carbonate) or any other green oxidation product.  So, it has weathered to a nice dark brown which may be a more authentic color for the critter than green anyway.
