You've never had a hamburger before?" asks Christine, her eyes wide.
"No," I say. "Is that what it's called?"
"Stiffs eat plain food," Four says, nodding at Christina.
"Why?" she asks.
I shrug. "Extravagance is considered self-indulgent and unnecessary."
She smirks. "No wonder you left."
"Yeah," I say,rolling my eyes. "It was just because of the food."
The corner of Four's mouth twitches.
