“If the decibel count in that kitchen had been measured when the father first instructed his daughter to hurry, it would not have registered at levels most people would define as yelling. The daughter’s reaction, however, is genuine. She picks up, senses, experiences the tension in the father’s voice, the edge of controlled impatience and frustration.

It is a matter of sensitivity, of the degree of reactivity to the environment. This child is emotionally hypersensitive.”
