As a human being living in the society,we should take responsibility for what we have done to the whole society. apparently, what we have done is much less than enough. maybe we cannot do a so-called great event.maybe we cannot change the entire world. but, i want you to believe that we are the master of the future, so we can bring our benefits to our friends, our neighbors, people who are trapped into a terrible y bad condition. by doing the little things we can also bring benefits to the society.that the reason why Laura Kallus recommend everyone of us to lend our hands to the people in needs.
