"How he met the family is not detailed." It's usually through a local church or other non-profit charity. These dumb bastards think the person moving into their home has been vetted and has no history of criminal acts, rape or drug or alcohol abuse.

Later these families learn how hard it is to evict someone who has not signed a formal lease when you've stupidly allowed them to move in for an extended period of time. Alternatively these host families learn what is feels like when the illegal alien steals everything of value from their home and flees back to Mexico in the family's vehicle.

Be aware of these organizations in your city and keep an eye out for fuckery. They prey on bleeding heart liberals and christian families alike.
