Silence speaks louder than talk

In our day to day life we meet with lot of people . some of them are important and some very important. ofcourse there are some people who have no importance for us. there are two kinds of people, one types of people remain silent and other types of people can say freely . When the second types of people are in need they can say it to others easily. sometimes they did got success but generally meet with failure. First kind of people always remain cool and calm. they always remain busy in their work. they hardly say something to others about their difficulty and need.
