Imagine you are the director of your state's foster care licensing division. Three applications arrive on your desk.

The first is a single, 23-year-old heterosexual male with a college degree in psychology. He is a part-time primary school teacher. In his application he asks to foster girls between the ages of 5 to 8. The home study worker and supervisor find no obvious red flags, but say they are "uneasy" about this applicant.
