It's not hard to get kids to talk. Given the opportunity, kids will spill their guts to an adult they like and trust.
We lived in a rough neighborhood for some time and I always felt sorry for the neighbor kids and would try to be extra kind to them and give them snacks, like cookies and stuff when they were hungry. I never pried for information either, but they'd just start talking and telling me all kinds of things that I'd rather have not known. Nothing that would qualify as actual abuse to them by someone, but just family politics that leave you just shaking your head.
But they will tell all if you are willing to listen.
Exactally. It works and the kids often don’t even realize what they have told you. You get more truth about what has happened that way than any other especially in a court room.
