The one where she argued back

Actual conversation between E and me last week in the car, driving home at the end of the day.

Me: Archer does have a race car toy. Gramzie gave it to him for his birthday.
E: No, it's a fire truck, not a race car.
Me:. You're not supposed to argue with me, remember?
E: I'm NOT arguing with you. You're arguing with me.
Me: What?! Are you being sassy-pants today?!
E: No. You're being bossy pants.

And that's the end of my story.
