At lunch, my friends and I complained about the intense heat. I said I would probably wear shorts the next day. (I perspire so much I get horrible chafing and blisters from trousers.) One of them said that might be against the dress code. I said it better not be, and fished out my handy-dandy student handbook, which we’d all been issued on the first day of the semester. Well, according to the dress code, shorts were permitted, provided the hem was no higher than a certain distance above the knee.
