The best response is no response. She just wanted to push your buttons. You didn't let her on the gun/badge thing so she moved to the area where she could get to you...the kids. It worked like a charm for her. Now, she's saying how worried she is about you. She gets to make herself feel better about her situation. Don't let her do that to you. It's late. Don't respond.
