Mangler sat back with a derisive gesture. "And I know why," he said with scorn.
"Indeed?"
"I do. You've sent through an appropriation for fifty thousand for your own fool—"
"I'm no fool, Mangler!"
"You are."
"If so, you are an opinionated idiot!"
"My opinion is quite valid."
"In your own opinion, your own opinion is valid. Stop defining 'A' in terms of 'A', Mangler; if I did that you'd be the first to scorn my definitions."
"What in the devil do you know about atomics anyway?"
"Only what you've taught me; if I'm a fool, it's your fault. What do you know about business?"
