A special robot

Lauren politely greeted Dr. Castafolte and shook his hand before sitting down, crossing her legs as she did so. A conversation soon began:

"So, Dr. Castafolte, what are you working on?"

"It's... I'm working on a special robot, but it's still a prototype yet.

"What is it?"

"As I said, it's still a prototype, so I don't know yet."

"Oh... okay."

"I apologize for denying your curiosity."

Unfortunately for Lauren, Dr. Castafolte had lied to her. At that moment, he was thinking of making either a mind-reading robot, a robot with x-ray vision, or a robot with human-like intelligence, as he felt the employees would be helped by it. He felt guilty for lying to Lauren, but he was afraid of her curiosity getting the better of her.

Should Lauren:

try to **** the issue,

wait for another day,

keep talking to Castafolte,

or talk to someone else?
