Arizonerak-
I think you have 2 choices. You can just avoid talking to this person about WI, or not talk to this person at all. If its who I think it is, she's not in any danger, but from what I know was in the perfect situation to be open to WI. I think you could mention it to the family in a casual way, and see what happens.
