The following conversation happened while I was not at home. It's a good thing too, because it isn't smart for moms to laugh at badness.

Mary, 8 years old—“Did you hear what she just said?!?!?!?”
Rachel, the one who was supposed to be watching them, from another room—“No, what?”
Mary—“She just said, ***whispers***‘good grief’.”
Lydia, 4 years old—“I did not say that!! ……..Guys, Mary is following my bad example!”
