For me, I'm having a hard time thinking kindly and offering the benefit of the doubt to both of BL's parents. In fairness, there is nothing particularly outstanding or offensive about their appearances, their possessions, etc., but in context to the situation, I'm finding all sorts of things to be judgy about. It's our human nature, I guess. Here's what I simply can not get past as a woman.
As a woman and a mother, RL should have called GP's mom *immediately* and told her GP didn't come back with BP; is she with you, is she ok? Or, if she knew GP was deceased, she should have told GP's mom..."Gabby didn't come back with Brian; something is wrong. I don't have all the details, but I wanted to call you immediately"
If she wanted to lawyer up after that, so be it. But a real woman would have called Gabby's mom. Gabby lived in her home! She was part of their family (or was she?). Not calling Gabby's mom is unforgivable. But no, she didn't call GP's mom, and Gabby was left outdoors to be desecrated by wild animals. Evil, pure evil, imo. What type of a woman, a mother, can allow such a thing? (Allegedly)
So it's easy for me to look at them with disdain and contempt and find all sorts of things to be disgusted with. I'm human.
