Psychological tests have showed that people with excellent or poorest abilities on a certain thing cover 2% of the crowd, and 95% of us are among the average ones. That means, God created most of us equally. It also inspire us with the fact that if you talk to a stranger, your chance to encounter a ruffian is far more less than to meet a common people. Talking with a common strange person can help us to absorb new information, and have a fresh understanding about the human nature. Most of all, we can feel the hopitality and trust between people. These active factors will help a lot in building your self-confidence.

When meeting a stranger, it's natrual to be curious and alert.  We told by our parents ever since childhood:" Don't talk to the strangers, don't eat anything offered by strangers." Well, we can not deny that there's some guys with evil intentions, but on the other hand, how to contact and communicate with others is a very important skill.   

As we all know, when talking with acquaintances, the way of talking is dependent on the social relationship and the other party's status. In most cases, we're not expressing ourselves according to our own wills. But the thing's quite different when it comes to talking with strangers. Less interestes between you and a stranger means less misgivings. Both of you know exactly that the one standing in front of you won't give you any notification nor prejudiceness.  Such equal and simple communication's essential to the personality builing of teenagers. Some children never become mature unless they left parents and schools, maybe talking with strangers can shorten the time for them to be more sociable and be used to the outside world.

Meanwhile, you won't mind your way and attitude when speaking to a friend, but if you meet some one for the first time, you should have the skill to start the conversation and get the ball rolling. You should consciously build up the relationship. If you're constantly doing this, your eloquence and interpersonal skills will be superior to your peers.
