On another forum, several people took issue with the last line of the chorus:
"That's why I got good stories to tell your grandkids."

Their issue was this: the rest of the chorus (as well as the verses) are directed to some grandkids, not to someone WITH grandkids.

I thought about this and see their point.

So now I'm singing it this way:
"Your folks they settled down and minded their own biz
I chased the high life and I caught the fizz
I'm not complaining, that's just how it is
It's why I tell my stories to someone else's grandkids."

I think that works better.
My wife and I have COVID, so my voice is shot. May be another week before I can record this version and see if I want to keep it.

(This would change the title, of course. I might shorten the title to "Someone Else's Grandkids")
