Chongo tells me that this is exactly what young chimpanzees (and some...ahem!... "mature" ones as well) do when they don't get what they want.

Yeah, it's funny. It's also kind of horrifying. I decided already by about age 15 that I definitely did not want to have any children, because I could clearly envision just those sort of situations arising in my future, and I absolutely did not feel I could handle it or bear it. Accordingly, I have never produced any progeny. As it is now in practical terms probably too late for me to do so anyway, I seem to have succeeded in avoiding this particular trial... (smile)
