Is it ladylike?

During dinner we were having some issues with the kid and using nice manners. Mostly Abby. So I told her "That's not very ladylike". Out of the blue she says to Evan and I "Stabbing is ladylike though". Umm.... Which of course prompted me to say, "No stabbing is not ladylike". I'm going to chalk that one up to too much vide game playing with her older brother.
