This is an interesting thread. I had my children late 20s, early 30s so they're only now settling down. I'm well past menopause, I must admit I found it unbelievably hard when, after university, they headed off around the world including spending two years in New Zealand. I'm not a lover of airplanes, never mind the cost!
I don't begrudge them their independence and I encouraged them to do whatever they wanted but I am now finding that being older means I can't do what I want either because I no longer have the physical capacity or, for instance, because I'm so far behind it feels too late to start. Also, life catches up, I'd love to travel but the virus makes it hard enough without additionally having to shield.
I can't walk far enough every day to have a dog but I did recently take on a rescue cat who is great to have around.
As to doing things with husbands? Maybe they're stuck in their own world??
