I think it’s just the way things are.
Oddly, our children push much more to do things, and go places than we do.
My cynical son says it’s because we always pay for everything, and I’m sure there’s a grain of truth in there!
But, they all seem to enjoy having us around.
I do see the day when the oldest grandchildren will start to disappear from our lives, and that’s to be expected, I suppose just make the most of things while you can.
I may feel more needy if I was on my own and retired, but I think I would try very hard not to show it.
So call your son, and enjoy your chat, you know what men can be like, he’ll be waiting for you to call because you always do!
