KPax ... my Boarding School had some nasty variations on Lines.
1. You had to purchase the special, yellow, lined paper from the Prefects' Common Room.
2. You were only allowed 7 words per line, so writing "I Must .. etc" 25 times down the page didn't work ... they made sure there was +/- 7 words in wot you rote!
3. Usually when you handed it in, the b****** just tore it up without checking ... buy who takes that chance?
