My son froze my cards so I couldn’t even buy groceries. He thinks he controls our $42 million empire—but one call from the bank made me realize he has no idea what I’m about to do. First my credit card declined. Then my debit.

In the years since, I have funded scholarships quietly through the company for women entering automotive management and finance. I support a legal aid group that helps older adults facing financial exploitation by family members. I sit on panels I once would have avoided because I disliked public speaking and now find perversely satisfying. The first time I told a room full of mostly women, “Do not give your children access without structure, and never confuse love with leaving your flank unguarded,” the applause started before I had finished the sentence. That told me everything I needed to know about how many of us have learned too late.
