Our family is a cereal eating family. Cereal is our main breakfast except for birthdays and holidays. So I can see how multiple boxes of the same exact cereal get opened, I think. However, it does make me want to become a cereal killer at times. Once or twice a month I preform the task of "cereal consolidation."
I take this seriously.
How else will my cupboards be organized and I have enough room for the new cereal?
I've given up on trying to explain to the household inhabitants on the virtues of finishing the opened boxes before getting a new one. That kind of lecture falls on deaf ears, I'm afraid.
It's a lost cause.
I'll just be a cereal killer instead.
