Those same kids are the ones who are tempted to "pull the feeding tubes" and over medicate dear old mommy and daddy. My aunt cites an instance where that happened. She was the floor nurse, and when she wouldn't up mother's morphine, the greedy bitch of a daughter reported my aunt to the doctor.
Nothing happened to my aunt, discipline wise, but she did walk in to the room to hear some ugly talk from the daughter directed at her mother. Mother declined rapidly, and was dead within the week. That was a very long time ago, and my aunt will never forget.
My mother passed away in September 2003. I got a real good look at a couple of my children. My mom and aunt wanted to protect me from my then husband, so I did not inherit according to mom's will. I had to lay down after the funeral, and my oldest was hitting up my aunt for "her share" of the estate.
There is more, but that's all I'm going to say on that topic.
If you have decent relatives, why not provide for them if possible? What are you going to do with family heirlooms, if not pass them down to children and grandchildren?
