Courage does not simply mean people have to do big， great things in order to protect their country or even save the world. In daily life， little things can also demand and create opportunities for courage. In today’s societies， it is often hard to be courageous， because when people have to face an obstacle or problem， often they prefer to thoughtlessly tolerate it or try to hide from the problem， because they do not want to put themselves into conflict. People avoid problems and thus opportunities to be courageous not only in modern times， but they also did so during World War II， when many ordinary civilians drifted with the “main ocean” of hate， war， and silence rather than listen to their consciences and react.
