My kids all don't live in one place.
I spent 36 years raising them and it was a LOT of work.
In early sixties I missed them a great deal and thought I wanted them near.

But now that I am over being "homesick" for my kids, I quite enjoy life without them.

I know a number of women who think they want to live nearer their kids and when they do, they get there and the desire to be near them reverses in about 2-5 years.

Arms length is good. At 100 I may need them...but I hope not.
