Hmm, let\'s see

Who: Cerebrum, McKenzie, Nick
Where: La Regal de McKenzies
"Hmm," Cerebrum said as he reviewed the menu, "let's see. I do
believe that I'd like to have the soup de jours."
"Are you sure you wouldn't prefer the salad?" asked Nick, looking
slightly nervous for some reason.
"Yes, I'm sure I don't want the salad. I want the soup," Cerebrum
said plesantly. He was in a good mood.
"Are you absolutely sure you don't want the salad? It's very good,
you'd hardly know that it was grown in a hydroponics farm, rather
than a real one."
"Are my lips moving? I said I want the soup," Cerebrum said, his good
mood was begining to erode.
"Trust me," said Nick, looking even more nervous, "you want the
salad."
"Look, are you always difficult and obstructive?" Cerebrum produced a
notepad and pencil from one of his pockets, "why don't you tell me
about your childhood. Maybe this will help us shed light on the
problem."
"What?"
"I'm a psychiatrist. This is my business. Tell me about your parents?"
Nick, in order to avoid discussing his inner feelings with Cerebrum,
said, "You don't want the soup because the chef accidentally knocked
a box of rat poison in one of the soup pots, and we're not sure which
one."
"You know what," Cerebrum said, "I think I'd like the salad, I'll
have that instead. I never really wanted soup."
