So I’m not sure what exactly are you finding bad about this? Or did I misinterpret your post (specifically about the “anger”, why should describing a positive experience all around elicit anger)?
I think you probably are misinterpreting something.
I'm not saying it's bad. Just that the part that was good for the kids was different from the parts that were good for the parents.
People here saying "That sounds glorious" about 50/50 custody arrangements strike me as thinking about it from the point of view of how the parents experience it and not how the children are likely to experience that.
Everything I've read suggests that shuffling the kids back and forth like that ends up being distinctly negative for the children in most cases.
Thanks for explaining! I guess I expected a more tight/direct analogy to the original divorce scenario (kids feeling neglected because their parents left them with other adults in the lake house?)
