I completely agree with you about leaving them alone, because despite the fact that she is making dad's life a living hell, she is a very good mother and takes good care of the boys. it was just a fishy situation, and things dont add up.
But the concern was that it was 9am on a Sun when she finally came outside. Dad had been there since before 8am waiting and no one had gone into the apt. Those boys WERE NOT asleep because they have stayed with us many times and are up at 7am latest, and if she had someone there, she was breaking her own (and the court's) rules for overnight visitors, because she has no family in the area that would be there at that time of morning. Dad's concern was of course that she had an overnight guest after she had made such a big stink about it (coming at midnight to our house to pick them up out of a dead sleep after she had someone ride by and scope out my car in the driveway). So that was the concern. Dad knows she would never endanger them. Thats not even an issue.
Yes, they are VERY good at this. LOL. They can total my stuff too!!
