Please. Please someone tell me if it's normal for a girl child of 7 to be experimenting successfully with Passive Aggressive Commentary.
I would love to know.
I thought the first PA (passive aggressive) comment was a one off, so I just sort of looked at her quizzically and shuffled off.
The second PA comment was met with a bit of, "Whaaa...?"
The third PA comment was when I had to wake up and smell the coffee.

 Ev's PA Takedowns go along these lines:
Dinner is served.
She makes a slight face (open dissent at the dinner table is prohibited).
She eats while asking a question about your prep, like, "How long do you cook noodles?"
You, in all of your ignorant glory, answer her.
She huffs.
She eats- not alot- but enough.
After she eats, she asks for fruit.
She eats the fruit while happily chattering away about her day so you are lulled into a place of unsuspecting contentedness.
Then, when she sees you are relaxed and enjoying things, then- and only then- just she lets fly The Zinger.
"I sure do love fruit. You know? It's like, you never have to worry about how long you should have cooked it. It's always perfect"

sidenote: apparently al dente noodles are considered "raw" in her book.

Right?!?!?! The first time I thought, "Wow. That was eerily similar to a passive aggressive volley." Silly woman. Silly unsuspecting woman.
I should have known better.

So then,  how to handle a 7 year old with a perfect and stunning grasp of passive aggressiveness?
Anyone?
Bueller?

No really. Leave a comment, call, e-mail, messenger pigeon, text, telegram, smoke signal. ANY advice would be appreciated.
