I have one.
Context: I was an engineering director down in Silicon Valley. All engineering programs reported in to me. I was in very good standing, got promotions every 6-12 months, year after year, more responsibility, yada yada all that. But, I'd hit the glass ceiling, having been told there was nowhere for me to go. Coincidentally, I was the only female director in the entire, vast place.
My MIL had died after a grueling bout with cancer, hospice, that whole shitty, undeserved kind of end. My husband was unemployed, as he'd quit his job (also in engineering) to take care of his mother in another part of the state (as others have pointed out, another key thing that FU money enables you to do).
It was a busy Software Season at my job, so we cut our annual (and, as you can probably gather, desperately needed) vacation with friends short, returning home on Thursday instead of Sunday.
Lesson #1: Everything bad happens when you go on vacation.
Lesson #2: Never, ever, EVER cut your vacation short. Ever.
I returned to work on Friday and, by 10 AM, was in a meeting with my (guilty, semi freaked out looking) boss explaining that, in the few days I'd been gone, some man had been interviewed and hired to take a brand new VP level position over me, *and* take over my team.
But it gets better... wait for it... My boss said he "hoped I'd stay on" and "could still be the new guy's assistant."
I said "I am no one's assistant. I'm leaving." And then I walked right out of the room and over to my desk, where I realized I probably should have asked my husband about this first, seeing as how we now had no income, him not having a job at the time and all. I texted him and said "Got a sec? Think I just quit my job." He called me and the very first words out of his mouth were, "Want me to come and help pack up your desk? Nothing would give me greater satisfaction than seeing you walk the fuck out of that place."
And that, ladies, is the moment you KNOW you married the perfect man. Unconditional support, he didn't even need to know why, and income, we could figure that out.
The details that emerged in the hours after my boss's announcement were priceless, and even more damning. It turned out my boss's boss had not even interviewed and was totally clueless about this hire (who would report to him), and instantly started fighting it like mad. Someone leaked the results of the new guy's interview and found the majority of people had recommended "No hire" and done so STRONGLY. On, and on. Unmitigated disaster, and nice to watch from afar, happily ensconced in my FU fund.
