Stupidity met Wisdom:
“You claim that you are wise – she said. – Are you wise?”
“Yes!” – answered Wisdom.
“What makes you sure about that?” – cunningly smiled Stupidity.
“They say that you are stupid. Are you stupid?” – answered with question Wisdom.
“Of course not” – proudly answered Stupidity.
“What makes you so sure about that?” – smiled Wisdom.
