Sadly, I have seen numerous examples of this: Parents who can't say No and adult children who think they're entitled to raid mom & dad's wallet. It doesn't end until the parents both die. If these "adult-children" have siblings who work and are responsible there is huge amounts of resentment and anger, as well there should be. It's bad bad bad....
No, it doesn’t end when the parents die. Then these kids are angry the life insurance benefit wasn’t more and that the parents took that Alaskan cruise instead of saving “their inheritance.”
