Moral: Trust your instincts.
So, I just finished writing my post about Crackers and his newly formed coffee problem. I took a shower, and upon exiting the shower, Mr. Crum admitted something. He just remembered that he had finished his coffee before running errands. Crackers did NOT drink half a cup of coffee after dinner (although I'm certain he would if he had the opportunity - therefore that lesson still applies).
There we have it, mama was pretty sure that mug was empty, and mama was right. Trust your instincts!
