Being retired from the school district at the end of 2008 as a Maintenance Carpenter and both a "lefty"...this is new to me. Graduating from high school in 1961and never realizing the difference before... desk is a desk...and I sat at a desk designed for a "rightie" and never realized the difference before.
I will send an email to my old supervisor who retired a couple of years ago...and ask him if this situation ever came up before...and get back to you on this interesting situation.

Normally before giving my wife's 4:00 AM medication to her...I do check the board every morning.
