This is what happens when you sit at a computer screen with yr eyelids
coated in thick antibiotic ointment. `Negative reinforcement', which has
nothing much to do with the case, *does* imply disapproval, if not a smack
in the ear. I meant, as everyone will have realised through a cunning use
of semiotically rectifying negative feedback, `negative feedback'.
