When I was little, I was abused by a woman who was my neighbor. As I grew up, and still lived in the same place, I found out that she was watching a little girl who lived in our complex. I witnessed her (my ears) abusive the girl in her apartment. I called ACS that night. The next day a case worker came to the parents of the little girl. They did a home visit, and I never heard the little girl being abused again.
They still don’t know that it was me who called.
