I feel an immense sense of relief that I didn't have kids, I never wanted them.
That relief stems partly from the terror of being responsible for a helpless child, and worrying about them forever even when grown up. I have a terrific life without them. It is not a perfect life - whose is... but kids and the expense and time and often sheer drudgery and lack of sleep and so on that comes with them is not at my door.
As for care in an older age, I have EPOA set up, I have my will made, I have instructions for what to do with me like a DNR, and I have enough funds to pay someone or some place to look after me. My attorneys know what I would like. If it gets to that stage I won't know or care, I will just be existing anyway.
My nieces and nephews will be quids in when I pop my clogs. I love them all, but am so glad I could hand them back when I had the pleasure of their company when they were younger!
So now I am off researching how to do Brussels, Ghent, Bruges, the Menin Gate and Paschendaele by train for my next trip. No worries about child minding, school holidays and having to be away at the same time as all the other darlings in the world.
It is bliss, and no regrets whatsoever, ever, ever. 😉
