a political cartoon accusing some politicians being dunces
Most people think our chairman is a dunce, but in fact, he’s a visionary who believes that long term policies help the nation far more than cheap short term ones.
My teacher says everyone is a dunce when it comes to certain issues, for instance, a mathematician who can calculate faster than a computer may be a dunce in keeping relationships with others and an artist who can create the entire world on a piece of canvas may be a dunce in doing maths, and so on.
Some people, I suppose, act like dunces when they are in hurry to prove themselves to be far better than the rest of the folks.
