I knew you were going to ask that...it's an awful admission, but I can't remember! Suffice to say that the story involved a disfunctional teenager killing homeless people for 'kicks'. It may have had some deep philosophical message, but (a) we didn't think so and (b) a bunch of 13 year old boys was very unlikely to appreciate that finer point either. We have no objection to a bit of violence or gore - in a relevant context; they are studying 'Macbeth' for GCSE, but there's a point to the blood and gore there, and a point that is easily demonstrable to a group of adolescents. The alternative class reader that the teacher in question has chosen, 'Fleshmarket' is quite bloody and gory too, but again, it has a point to it. It's a great blend of history and fiction set in the Edinburgh of Burke & Hare.
I can quite believe it. I am sure there are thousands of households that do not even possess a good dictionary or encyclopedia.
