Yes, Friday, they do. But believe it or not, even though they and the rest of the family have cut off all ties with that brother (he doesn't even know what state they live in now), every once in a while they say they still love him. Which I will never understand, but as long as he's out of their lives, I don't care. Myself and my other brother and sister now have the best relationship with our parents that we've ever had. They see what they did, and they've expressed deep regret to us about it. It's just incredibly sad that it took something so horrible to bring that about, though.
Anyway, I guess how this relates to the A family, is that for a lot of parents, the love they have for their child seems to withstand almost any evil act that child commits. Hard for me to grasp, but then I've never had to face that myself so who knows if I'd feel the same?
