Funnily enough, the kids who go on holidays do give a crap about them.
They get really excited, and look forward to them. They love them while they’re on them - they love revisiting places and people, and exploring news place. They look back on them and the photos with happy memories, and then, once again, love looking forward to the next one. And the cycle continues.
Those memories are priceless.
I can’t think of a figure for me personally. We’re both on 6 figures, and are both able to work flexibly. I either WFH or leave the office in time to be home for the kids - I did school pick-ups when they were younger (now they catch the bus, but I’m home when they get home).
Between DH and I, we both have the flexibility to be home if someone’s sick, or to attend school events. The more you progress in a career, the more flexibility you tend to get.
So I can’t really think of a figure that would be worth giving up my salary, pension, and safety net, should something ever happen to DH (he had a heart attack in his early 40s, so this isn’t just some abstract idea to us).
