Abstract
Consider the following situation. It is the first day of school, and the new third-grade students file into the classroom to be shown to their seats for the coming year. As they enter, the third-grade teacher notices one small boy who is particularly unkempt. He looks to be in desperate need of bathing, and his clothes are dirty, torn and tight-fitting. During recess, the teacher pulls aside the boy's previous teacher and asks about his wretched condition. The other teacher informs her that he always looks that way, even though the boy's family is quite wealthy. The reason he appears as he does, she continues, is that the family observes an odd practice according to which the children do not receive many important things – food, clothing, bathing, even shelter – unless they specifically request them. Since the boy, like many third-graders, has little interest in bathing and clean clothes, he just never asks for them
