Forced to leave this week's Quality Assurance Agency conference in Glasgow early David Miller, chair of the Scottish Qualifications Authority, said he was relieved that this would spare him any reaction to his presentation. After another recent presentation, a friend told him how dreadful he had been. Seeking reassurance from another friend, he was told: ``You don't want to bother about what Jim says. He hasn't an original thought in his mind, and only repeats what everybody else says to him.''
