I'm no idealist about this. What did this "lesson" teach me?
1. Mr B. whacks bloody hard.
2. Mr B's plimsoll bloody hurts.
3. I don't like getting slippered by Mr B.
4. Mr B. is a bully.
5. I'd better not misbehave in class again if I don't want another of Mr B's slipperings.
6. If I ever get to be a prefect I'm going to be a mean bastard like Mr B.
7. It's not fair that girls don't get the slipper.
8. Thinking about getting slippered by Mr B. and girls getting slippered is getting me all excited.
9. Wonder if my girlfriend will let me spank her tonight?
10. I wish I could see Lotta N. getting the slipper from Mr B. on the seat of her navy blue knickers.

Just as I suspected. Honest answers. Nice. Although I suspect #5 should actually read "I'd better not get caught misbehaving in class again if I don't want another of Mr. B's slipperings." Subtle but important difference, I think.
(Dave start) See? Didn't do me any harm at all.(Dave end)
Oh no, not any harm at all.

I would have had fantasies of poisoning Mr. B.
