Stupid. It's what's for breakfast.

Scene: our kitchen; 7:00 a.m. Devin & Conner are at the counter, eating breakfast.

Mom: (shuffling out, bleary eyed, to make some coffee...) "Good morning guys."
Devin: "Hi Mom. Listen, there was a little mold on this bagel, but I cut it off. I'm trying to eat it, but it tastes bad. It tastes funny. What should I do?"
Mom: "Don't eat it." (desperately fighting the urge to add 'duuuuh')
Devin: "I thought you might get mad."

Note to self: Make an addition to the Lessons To Teach The Children list.... There is a difference between wasting perfectly good food and throwing out food poisoning that is disguised as a bagel.
