Dear half-siblings,
Honestly? No, the amount of money my parents seem to spend on travel and entertainment does not concern me. It shouldn't concern you, either. It's none of our business.
They've told you on numerous occasions that their burial arrangements have already been handled, so no one need be concerned about that. Their house is paid for in full, they have no out-of-pocket medical expenses because dad spent 30+ years of his life serving in the military, they only make big purchases with cash, the two credit cards they have are paid in full every month, and they spent their entire working lives together planning and saving for their retirement so they have a pretty decent handle on their finances.
In case you need a reminder, dad is 82 years old now and he has cancer...on top of plenty of other issues. He also loves to travel and gather new experiences, so that's what my mother is trying to make sure he gets to do in the time between all of his medical appointments, tests and scans.
If this is how they want to spend their money, shut up and let them have at it.
Somehow, I think your concern is less about their financial well-being and more about how much you think you'll be getting after dad passes. Buttheads.
Annoyed,
