No doubt some of you wouldn't even know how to deal with this behavior if she was your cute young friend.
*Squints out into the depths of the internets*
You all know who you are.

As for me, I had to stop fanning myself over how well this cutie pretends and how sassy it is to me, and remember that the point of the video was *NOT* t to let your kid or your YF act this way, especially for real, and especially in public:

I'd have to sit her down.

"..and so in conclusion, young lady, this is acceptable behavior with me, but not in public, and only when we're playing around, but not when I'm trying to be serious with you. It's also fine to act this way toward meddlesome busybodies who stare at us when you wrap your arms around my waist in public, and to snark 'What are you looking at?' or 'Take a picture, it'll last longer!' ..but in all seriousness Ava, generally speaking this is highly improper behavior, and it also gets me very worked up. So now that I've made things clear for you, I am ready to answer any question you might have over a relaxing candlelight glass or two of sparkling grape juice."
