Life is ironic by design. Your body is ready to reproduce years , even decades, before you are financially and emotionally ready to be a parent. By the time you are in your sixties and have gotten over how unique you are and you have fought for you independence and hopefully gained it , that is exactly when you want, no need , closeness and nurturing.
You turn to your kids and they squirm because they are all about establishing their own independence and they do not want to be burdened by your needs.
If you are in my socio economic bracket, you probably left the suburbs after your kids were born but before they had to go to school. You could not afford to stay in the city and ensure a good education for your child. If you are like me, you learned to appreciate the relative peace and quiet, the backyard, the pool in the summer, the local beaches and parks.
But ironically just as your house is done to your liking,  just as maybe your mortgage is paid off or at least you can count down to that day, you wake up and want to chuck the whole white picket fence thing and move back to an apartment in the city. You want to walk everywhere. You want your super to have to shovel the snow and get your walls painted. You are willing to give up the two cars and rent one when you need it. You want to go out for breakfast coffee, You want to sit in cafés and people watch. You want to be part of a cultural Mecca and hear lively discussions about the work other people are doing.
But you have grandchildren. And you want them to come for the holidays. And you want them to move somewhere nearby so you can be useful again to your family in a meaningful way. You want to pass culture down and your kids can’t do it because both of them are working and they don’t have that to give. You are wiling to fill that void.  But your children want their independence.
Of course I am talking about my situation. But I would be happy if you shared your experiences.
