When something hurts, we say OUCH! Is that genetic? Is it a natural pain noise?
No--it comes, some think, from the Pennsylvania Dutch word for yow!
Or from some ancient language--no one seems to know.
Does this vary from culture to culture--not really. Ouch seems to be it.
Now--tell me why we say "Well..."
Do we mean, "Hole in the ground, no one knows...?"
