Helen sipped a Scotch and checked what she called her "must" list. "One of us," she was saying, "has got to make another trip to town. I have to have detergent for the dishwasher and washing machine, soap powder, paper napkins, toilet paper. We ought to have more candles and I wish I could get my hands on some more oldfashioned kerosene lamps. And, Randy, what about ammunition? I don't like to sound scary, but..."
As you can see, Helen's list is completely appropriate. She has focused on necessities/ not luxuries. If I were to add to her list, I would probably begin with emergency medical supplies..... a well stocked first-aid kit.
