My fathers funeral. He and mom were in a car crash, mom was incapacitated, no one had access to anything so we footed the funeral bill until everything was sorted out with insurance and accounts etc.
Mishmash: I'm so sorry to hear about the loss of your father. I hope your mother is better. What a blessing you could give your family to be able to pay for this and for folks not to have to add it to all their worries.
Mishmash: Another round of condolences from me. What a gift to the rest of your family at such a sad time.
On topic: I do not have a category called "Emergency Fund". I have one called "Reserves". Pre-FIRE, I was in commission sales, so I was always trying to accrue as much as possible and stay a couple of months ahead. I am often swimming in cash. (FWIW, my MO is to accrue/sweep into investments/repeat.) I can't think of a single personal emergency, but that might be because when one has "Reserves", nothing's really an emergency, which is damn nice.
I can think of twice that it's helped family members out in a pinch:
1). I took my parents to look at model homes in a new retirement community. They found one they liked. The builder offered an extra $25k off if they put a deposit down that day. They didn't have that much on hand, so I wrote the $10k check. They paid me back a week later.
2). My brother was in escrow on a home when the deal fell apart on closing day, due to his lender's colossal fuck-up. He called me in a panic and I moved about $200k* into his account that day so he could pay cash for the house (we have the same bank). The house closed. The lender pulled its head out of its ass, funded his loan and I got my money back the same week.
*Hell, no, I don't normally keep that much cash on hand! I had just sold a house and was in escrow on a new one that was a short sale. Since that escrow lasted an agonizingly long eight months, I had plenty of time and cash to help my brother out.
Tl;dr: Springy debt, my ass.
