Beware the person who asks no questions, for that person has thought long and made a deliberate decision from which he cannot be swayed. Alternatively, that person has not thought at all and his ignorance armours him in certainty and delusion. Or, finally, the person who asks no questions lacks the strength to reveal a vulnerability or a weakness to his audience.
In any case, a person who asks no questions is suspect.
