The poster who's neighbor keep asking for rides to school for her children and even break into her home and sit on her bed to wait. Did she ever start up again?
That was me! I had a very hard time getting Carla to stop, and her escalated before we had a massive fallout one day.
She came into our house (uninvited as usual) and *yelled* at my son for playing with a toy gun. She accused him of making her feel unsafe and just acted generally hysterical , so I firmly instructed her to leave.
As I walked her to the door, I saw her son trying to set my garage on fire (again!!) and I told her to get out and stay out - or I would call the cops.
She left us alone after that, and trips to school was wonderful :-)
I wish I could have dealt with it in a better way, but their behaviour was just so out there that I really had no choice.
