"Have you ever been in love?"

She didn’t see the point in the question. "I care about people."

"I don’t know," she begrudgingly admitted. "Is it?"

"You never can tell until you’ve noticed the difference."

They continued in silence. She thought on it, for it must have been possible to show the Underworlders the difference.
