I answered with, 'He just drove there,' I think I was supposed to infer a night time incident from the context but it didn't work. The person asking got a bit mift at this point, she was never the brightest light on the Xmas tree, not dim exactly, she just put too much faith in rote, one of those folk with predicable thought processes who accepted answers depending on the status of their source. Anyway I tried out the question myself, for curiosity's sake, guess what, it didn't work then either. She must've been asked the question herself at one point, for her to be as impressed by its implications as she seemed. So I started to wonder, was the question posed to her with a more effective wording or did she fail it deliberately? By deliberately I mean, appear to make the assumption of a night time context in the question, for the sake of social acquiescence, then use self deception to convince herself that her assumption was genuine. That might seem a little tenuous but the nature of her reaction, when I failed to make the elicited assumption, was something akin to that which follows from a break in social etiquette, it was if I was being rude.
A much better question of this ilk is: if a tree falls in the forest and no one is there, does it make a sound? Yeah that question, this one went so far over my head that I always dismissed it as some zen type thought mangling, that needed sufficient drug induced cerebral hindrance to be effective. It wasn't until it was pointed out, that the word sound, a bit like the word colour, can be, and is often interpreted as reference to a sensory phenomena, that the penny dropped for me.
So here's another question, that falls somewhere between the forest question and the equivocal wording of the car hits deer question. Here it goes: there are three people travelling together, each of them has just applied for a job as a bus driver. The first person is a good driver and got the job. The second person is a fair driver and didn't get the job, the third person can't drive. Who wins?
