I have two different views of this prof for you to consider and therefore two photos that need to be filed in the right place. The computer in the first view may help place him in time. I was curious about the sign below the prof in the computer picture so I enlarged it and it reads:
IF YOU ARE UNABLE
TO CLEAN UP AFTER YOURSELF
YOU OBVIOUSLY ARE INCAPABLE
OF USING THIS COMPUTER SO
GET OFF IT!
(OR LEARN TO LEAVE A CLEAN WORKSPACE BEHIND)
So was it the prof that was anal or someone else?
