That's an interesting question. I might have been reasonably blunt about the situation to the less dominant person if I'd seen the problems coming. On the other hand, she was the less dominant person, and I don't know whether I could have said anything general that would have helped. If I'd known the outcome of that business in clairvoyant detail (lost money, lost friendship), I think it might have registered, but there was no reason to think I would have known that much.

After it all fell apart, I read in The Millionaire Woman Next Door that it was a sort of business (gift shop) which is especially likely to go under. That might have been useful information. As I recall, the book has bankruptcy rates for different sorts of businesses.

In retrospect, I don't think they were technically prepared, either-- but I didn't know enough to evaluate that.

In general, it's hard to get good advice.
