We thought we were soooo clever in second grade when we figured the elderly nun was virtually blind and had our desks memorized as to who sat where. We switched seats to test our theory. That trial didn't last long when we realized we were getting dinged for what the other kid did.True story... in a highschool typing class I had a very elderly teacher, she wasn't all there... Once a kid climbed out the window, went around and knocked on the door. When Mrs. Red answered the door the kid asked to see himself. Mrs. Red because visibly upset when she couldn't find him. Thankfully she retired that year...
That said... the 2 highschool classes that have served me more than all the others were the advanced math (calculus, algebra) and 2 years of typing.
With the proliferation of computers... every moment I spent in typing class has paid for itself many times over.
