"Who were you out with?"
"Brannan."
"Then you didn't get to bed early! If you got in by three, it would be early, if I know Brannan."
"I got in much before three!"
"How much?"
"Oh ... enough. You'd be surprised...."
"I'm sure I would! Mary, how do you expect us to get anywhere with this experiment if you come in dog-tired?"
"Donald Jensen, I'm not dog-tired. It's you who's got me in bed in the wee hours, not me! I came in early."
"Then why won't you state the exact time?" he was exasperated.
She smiled at him archly. "I don't remember, exactly."
