Why is it that somewhere, someone allegedly an educator, can be relied upon to do something profoundly stupid. In response for what passes for a heat wave in the UK, students wished to wear shorts. A perfectly reasonable request under any circumstances. But the alleged educator-in-charge ruled that this was not to be and trousers were to be worn. Then she made a mistake and said they could always wear skirts if they desired. And so they did. Good for them.
Of course, perhaps this is a good thing, another one of life's little lessons learned. Those in authority are perfectly capable of sublime stupidity.
