Take off any offending clothing

"Any articles of clothing which contravene uniform policy are to be removed," the headmistress continued, "and not replaced for the rest of the school day."

"Miss?" Sandry was shocked.

"Take your trousers off, Smith. If you can't wear ones that fit, you've lost the privilege of wearing any."

"But... But everyone will see my knickers!"

"They've already seen them, since you came to school in clothes that can't keep your bum in." The headmistress took Sandry's shoulder and turned her so her the split rear seam of her trousers faced the school again, to more laughter.

"Please, Miss, don't make me do this..." But Sandry could see there was no arguing. She fiddled with the fastenings of her trousers, finding them stuck at first but then suddenly the button popped off the material and bounced away, a milisecond before the zip parted its teeth, broken. Sandry looked at the headmistress who raised an eyebrow, her point doubly proved.

Sandry bent forward, lowering her trousers to the floor.

RIP!
