Why bother?

Who among us hasn't been reminded by an office manager cum den mother/father to "PLEASE, whoever you are, press the "clear" button when you are done using the microwave!!!!"? or by the weird lady in Accounts Payable carping about some stolen highlighter pen that apparently had sentimental (emphasis on mental) value? These "friendly reminders" are often dismissed with a "she/he's nuts" but I think that, en masse, they can allow for some good laughs and, dare I say, (yes, I shall) closure.
