She hesitated. "I mean, no, but—"
Her phone buzzed again, this time with a call. She glanced at me apologetically. "It's Vivienne. I have to take this. She never calls unless it's important."
Before I could object, she answered. "Hi, Vivi! What's up? ... No, I'm at school, in the library with Isaiah. He's helping me with calculus ... No, I haven't forgotten ... Yes, I'll go with him to pick up our dry cleaning after school ... Yes, I know the blue dress is for Saturday ... No, I won't let them press it wrong like last time ... Okay, love you too, bye!"
She hung up and sighed. "Sorry about that. Vivienne's stressed about the Lumière launch party and she's turning into a tiny dictator."
I tapped my pencil against the table. "Harlow, I think I see the problem."
"With integrals?"
