Yep, that is me. I have told them repeatedly to have a switch installed so a generator could be hooked up. When we got our whole house generator I gave them my electric start 10K genset. But did they listen. No they did not. So it will be me hauling gas and stringing extension cords all over the place.
The impression I get was that this trip was unexpected on your end that was pre planned by your daughter.
You told your daughter and her husband what they should have planned for, they did not listen to you, and now you're the one taking care of their lack of planning.
It sounds as if your daughter and her husband are financially sound and not strapped for cash.
There is one saying that my father taught me that I never have forgotten... "piss poor planning on your end does not constitute an emergency on my end".
What I find head scratching is that that it seems like your daughter kind of expected you to do this. This no less right after your were taking care of her daughter while she was away on a business trip and she's over at your house at 4AM to pick her up?
You say "you are going to talk about this" (apparently when they get home). Given that you bought a car for your grand daughter and then she isn't to tell anyone about this and then have another grand daughter ask you to plan and pay for a family vacation for 11 people, I'm think whatever talk you have to your grown daughter is going in one ear and out the other (that said, if the grand daughter is the same person on the car and vacation, with all due respect, she's spoiled IMO).
Apologies for being critical on my end. Of course there is no right way to raise kids, and kids are like farts, they aren't as bad when they're your own. Sounds like you have done a remarkable job in raising your children being productive members in our society, so you must be doing something right.
My dad grew up poor with his parents off the boat working in the coal mines before he was born. He (dad) saved and taught me that nothing is promised to anyone. That said, after my mom died and he (dad) was by himself, he was always wanting to spend money on me and my wife, which I generally always refused because I told him he taught me to not to rely on him (added that I had my own career and was making more money than he ever did when he worked, and my wife actually makes more money per salary than I do LOL).
This is where I guess we differ as I viewed it as my job when I got older that it was now my responsibility to take care of my dad since he took care of me for so long and for myself not to be a burden on him in his older age.
Reality is I'm more upset at your daughters apparent expectations of you and what she assumes of you because you're her father, and that is not my right on my end.
