There is a woman in America who had a monkey many years. The interesting fact about this monkey is that it can wash plates for the woman every day. He likes to wash plates. He will spend hour after hour washing plates. He never breaks a plate. But sometimes he washes the same plates over and over. If the woman tries to stop him, he then gets angry. He begins to throw the plates to the ground. But this doesn’t happen very often.
