It is important that you know the people she will be staying with. Do they have firearms safely secured, do they have a working smoke alarm and carbon monoxide detector, might someone in the home abuse a little girl? I would want to have visited their home if possible, or at least meet the parents to form an idea of their trustworthiness. The questions we need answers to aren’t ones we can comfortably ask openly, but hopefully we can get a good idea of a person’s character by spending time with them.
