When my sons lived at home, I'd hide chocolate in the freezer behind the yeast. I figured my boys wouldn't have any interest in yeast, but I'm not 100% sure that they didn't ever find the chocolate, since they all show signs of high intelligence, and I could never remember how much I'd left from my previous raid. (There was always some...)
So I can understand why Carolyn felt the need to mark the food she saves in our fridge. After all, Bob eats stuff from the refrigerator, and so do I. If we don't know it's hers, well, then, we might just eat it...unless she writes a message on the plastic storage container in permanent marker!
Do other people eat your food?
