Normally I avoid explaining the obvious. But I will try.
When an eight year old girl suffers anything resembling a disturbance in her emotional fabric, they shriek in a very high, very loud voice that sounds similar to the device the original poster called a "black box".
I was juxtaposing the two, which should have resulted in a spontaneous jiggly feeling in your diaphragm. Obviously, your brain processed the two as being completely unrelated.
Not your fault, of course. We all have deficiencies.
That's strange because my seven year old got over that two or three years ago. But then I guess neurological development occurs at different rates in different children, as does intellectual and moral development, which results in a suppression of those primal brain stem impulses in the quick learners.
