When I first started I did my interviews with the kids there and it was definitely not ideal! And then I thought about the safety concerns and since then only do evenings or weekends (weekends are better for me because I have young kids of my own and evenings are when they need my attention most). I also make sure my husband is home for interviews. Not only is it unsafe to be alone in the house with strangers (again, not likely, but if they turn out to be axe murderers, who would hear my cries for help?) but it also gives them a chance to meet him and it helps them feel comfortable with us as a family because their kid will see my husband coming and going and it is sometimes a concern parents have.
