Mr. Edgar: How was your feeling, Ma'am, when the President Director appointed you to this position?

Mr. Edgar: I'm sorry, but did you just say 'shy'?

Mr. Edgar: May I know what research the department has been doing lately? .

Mrs. Yunita: WelL It is still the secret of my company, but let me ask you. Are you busy lately that you don't have time to do chores?

Mr. Edgar: I am. That is the problems of many people today.
