How do I address people asking about my mother?

[Guest guest]

I have been catching up with some old friends from my school days. The ones who

were close enough to my situation were not suprised when I said I no longer

speak to my mother, they saw it when I was a kid.

But there are some acquantainces who even had parents that were sort of friends

with nada. They are going to ask how she is, and I need a very simple one line

sentence that isn't dishonest, but doesn't give details. I am not good at

wording things. I don't want to say " I no longer speak to her " but I don't want

to say " oh, she's fine. "

Any advice on steering clear of the judgement I'll get on this, without dodging

the question all together, which I think would be more obvious, esp if these

people have " heard thru the grapevine.. "

Thanks.
