Be still, my vassal

My dear sweet child, my darling baby girl... How I am floored by thee.
Just a few moments ago, as I stood over a heaping basket of clothes, most of them belonging to the children, folding and hanging at a fevered pace, my darling daughter came into my room. I gave her a plastic bag and asked her to pick up the trash that she and her brother had littered the floor with, mostly drawing papers and bits of candy wrappers.
She bounced up and gleefully grabbed the bag, in an obvious gesture of gratitude for me seeing to her every need, every single day of her little life. NOT. Nay, she dropped to her knees, bag in her hand, and started crying. Not just any crying mind you, she had to articulate. "I don't want to do this."
To Which I explained "Well, I don't want to do laundry, either, but we have to get it done." This is where I pat myself on the back in my mind, for coming up with a perfectly logical response to her protest. Much to my surprise, my logic fell upon deaf ears, maybe due to the fact that she was crocodile crying to drown me out.
Then she said it... "I can't believe you are using me as your slave!"
Hold for the dramatic pause, as I checked with my ears and, yes, in fact, she DID just say that.
Are you kidding me?! Slave? SLAVE?! USING?!

Holy shit, hold up! My brain was a whir of reactions- like a computer looking for a solution to a problem amongst a million possibilities- going down the list. I dropped the shirt I was hanging back into the basket, and whipped around to face her. Did she take note of my bewilderment? Of course not. She was still whimpering out what was now a long string of nonsensical blubber. All of which, I am sure, was somehow characterizing me as a modern day Simon LeGree. I was still stupefied and had little response to the comment of her serfdom.
Without much comment, I took the bag from her, and told her to go take a nap, and that she hurt my feelings by saying that. Her wailing only became louder as she screamed down the hallway "You don't love meeeeee...." and then the door closing behind her.
There have been many days that my kid's comments or actions have caught me completely off guard, either with the outrageousness or cuteness of it all. Nothing like this.
Since the event, she has come to me and apologized for "Taying that, and hourting yo feelins".
What is it... that saying about the mouths of babes?
What am I to do with those kids?
