On the first day of your Senior High you must meet many new classmates. Do you want to make friends with them? Do you know how to make friends with them? The following article will tell you how to do it.
Making friends is a skill. Like most skills, it improves      practice. If you want to meet people and make friends you must be      to take action. You must first go to places where there are people. You won’t make friends      at home alone. Join a club or group, for talking with those who      the same experience as you is easier, and      them in some activities.
Many people are      when talking to strangers. After all, meeting strangers means facing     , and it’s human nature to      a bit uncomfortable about the unknown.
Most of our fears about dealing with strange people      from doubts about ourselves. We      other people are judging us, thinking us too tall or too short, too this or too that.     , don’t forget that they must be feeling the same way. Try to accept yourself      you are, and try to put the other person at ease. You’ll      feel more comfortable.
Try to act self-confidently      you don’t feel that way      you enter a room full of strangers, such as a new classroom, walk straight, look      at other people and smile. If you see someone you’d like to     , say something. Don’t wait for the other people to      a conversation.
Just meeting someone      doesn’t mean that you will make friends with that person. Friendship is      on mutual(相互的)liking and “give and take”. It takes time and effort to develop. And there are things that keep a new friendship from growing.
