A number of years back I was going to school while raising four kids and keeping up with my Air Force husband, I would on occasion be too busy to unpack groceries as soon as I got in the house. So I would unpack only those things that needed to be refrigerated or frozen and leave the bags with the non-perishables for when I had some time. Once, those bags of canned goods, etc., sat waiting for a couple of days when we all began to notice a very unpleasant odor in the kitchen. Finally, we zeroed in on the bags waiting to be unloaded - I had over looked a package of frozen broccoli in the bottom of one bag which, of course, had thawed and begun to spoil. Took ages to get the smell out of the house and for everyone to stop teasing me! Ugh!
