介绍： When psychologist Hal Herzog's son Adam was young, he had a pet mouse named Willie. One day, Willie died.

"When he died, we thought it would be a good lesson for the kids in terms of understanding death to have a funeral for him. After all, you know, he was a pet."

But a couple of days later, Hal's wife found some mouse droppings in the kitchen and asked him to do something about it.

"She asked me to kill the mouse, and I did," Hal recalls. "I went out, and I bought a mousetrap. I put a little dab of peanut butter on it and put it [in] the kitchen. And, the next morning I got up, and the mouse was dead."
