White Out

Sometimes modifications require specialized equipment. Today, that equipment was in the form of Liquid Paper. Commonly known as white out. My student was confused when reading a clock paper. The time read 09:00. Being the professional I am, I took my Liquid Paper out of the "locked" cabinet and whited out the 0 in 09:00. Suddenly, the time was 9:00 again. Thank goodness for white out.
