It doesn't matter if your parents have been grown up since well before you were born. It also doesn't matter if they've never been financially dependent on you. You will be paying the nursing home bills if your parents are indigent, and if you don't have the wherewithall to fight the home in court.
Now, family does for each other and it bothers me to see some folks in my neighbourhood dumped off at the home at the first sign of trouble. And somehow then wow, grandkids have "bought" the house at an amazing low price. (I truly believe God is gonna judge that.)
That's family for ya. You don't want to give "family" too much power (good or bad) over one another's finances. But if we can help a family member in a bind, we sure will. Our little family, though, doesn't have a million bucks in the bank account in case somebody's health goes south next week. I'd make a crappy caregiver, too, because I can't even lift the groceries any more. I have to have my older children help me.
I'm sure hoping my parents and my husband's have good insurance because the best I can do is offer moral support and maybe a $50 gift card at Christmas. Hey, at least I don't do the "nightgown and slippers" gig.
