I think she is right that people don't like being reminded that things go wrong. Thats not a reason to stop talking. Good grief. It all comes down to delivery.

Sell Benefits/Results and it makes more sense. Instead of saying, "If you don't buy a generator you will be without power if yours goes out." While true, people look at it like Chicken Little. When delivered as, "Those that physically, psychologically and emotionally did the best after XYZ event where those that were able to meet the needs of their family for food and warmth...from a generator." blah blah blah.

Screw her, I'd go to em.
