I think the other thing is, that our adult children don’t see us getting older. I don’t know about any of you, but I try and be as independent as possible, never alluding to my age, I don’t ask for help, and I’m sure they assume none is needed.
My husband and I are both in our mid sixties, no serious health problems, and both still working, and I don’t think our children see any difference to how we were thirty years ago.
So I agree with others, if you want something doing, just ask. Your son sounds like a nice chap to me.
