What a sensible person does

There was a silence. Then Serapta said, “That woman is as crazy as a loon.”

     “She’s not, Serapta. In fact, she’s using reason—”

     “You call that using reason? To want to do a terrible thing like that?”

     “Well, what does a sensible person want to do? Save their life if they possibly can. That’s built-in instinct,” Hindle said in the tone Doctor used to use when trying to teach her something. “If they got a problem, they want to solve it. If there’s doubt, they want to clear it up. If a thing needs settling, they want to settle it. A sensible person uses their faculties.”
