True story: when I was growing up, my mother and a close family friend (who was a grandmother-type-person to me--my "GMTP") purchased a duplex together. We had the top floor apartment and a re-done attic bedroom that was mine; she had the bottom floor apartment. We had a cat, and, to save $$, my mother often made our own cat food out of usually tuna and (appropriate) veggie scraps. She would then sometimes freeze it in the chest freezer that GMTP had in her half of the house.
One night, my GMTP, who was in various classical musical groups (she played the recorder and french horn) was hosting a group for dinner in her apartment. She often hosted these kinds of impromptu dinners, and would, in anticipation of not knowing when they were needed, would make salmon and tuna loaves periodically in advance and then freeze them to use for these kind of occasions.
If you haven't figured out the punchline to this story yet......yes, without my mother knowing until after the fact, my GMTP did end up thawing, baking, and serving one of the "cat food" loaves, thinking it was one of her tuna loaves. The good news is that my mother is such a good cook that, while my GMTP thought it tasted a little off/different to her, none of the guests commented, they finished their servings, and no one got sick. The guests were none the wiser.
They both did a better job labeling what went into the chest freezer after that, LOL!
