A friend on Fbook was bemoaning the stress-inducing state of her country the other day, and said, "... it would be way less so if I didn’t have kids and didn’t have to care about the future of the country/world/etc ..."
I didn't say anything, though I was sorely tempted, and I am still tempted to message her and call out her comment. No, I have not raised the next generation, and no, I don't have my own genes going into the future, but it is a huge presumption to say I don't have to care about the future of the country/world/etc. I of course care deeply for my nieces and nephews, and for any children they have/well have, and I grieve for the future they will inherit, more so it seems than some of their parents, or the parents who are doing their utmost to divide and destroy.
Furthermore, perhaps precisely because I don't have children who will inherit my name, my genes, my outlook on life, my legacy is the legacy of the country, of the planet, of the human race. It is not focused on my own progeny, but on everyone else's progeny, including hers. I can't shrug my shoulders and focus only on my children, forgetting about wider issues. Leaving the planet a better place - kinder, more aware, more thoughtful, for example - is my only legacy.
