Remember that being strong, not enabling, is what you are doing for her. Imagine when she learned to ride a bike. Holding the bike up from behind is only helpful for so long. Then its preventing the child from learning and ultimately causing them to be unbalanced. So rescuing her is preventing her from developing skills to pick herself up. Businesses fail. People move on. Moving on and not wallowing in failure is a skill.
As a former financial professional I see this differently. I'm sitting with a daughter who asks about her parents. I'm obviously not going to discuss one client with another. To say none of your business is rude and unprofessional. What can I say? I stop the discussion by inferring, though I don't really believe it, that she's asking out of concern. So I say you don't need to worry about them. Its not a suggestion of anything about another client. Its a non answer response to a daughter. After all, she knows I am a consultant to people with money, not a bankruptcy attorney.
