The Opposite of Sass

Me, standing behind Sarah brushing her hair in the bathroom: How do you want your hair?
Sarah: How about a side pony?
Me: OK. Which side?
S: Either one.
Me: OK. You don't have a preference?
S: Whatever side you think looks better, then I'll like the opposite.
Me - arching an eyebrow: Excuse me?
S: What?
Me: You'll like the opposite of whatever I like?
S: Yes. Because I'm looking in the mirror.

(I should have known my sweet Sarah would not sass me like that!)
