     Sometimes,  even the best friends have fights.  They  disagree with  each  other and begin to  argue .

Sometimes, they even stop talking to each other.

     What can be done to help the two friends make up? Finding a good friend who knows both of them

very well to be a peacemaker is a good way. Maybe one day you  will be a peacemaker for your good

friends. Here are some useful communication strategies for you to use:

    ◆State your feelings clearly but don't criticize them.  Begin with "I feel. . . " instead of " You always. .. "

    ◆Don't stop or finish the other person's sentences.

    ◆Listen carefully to what the other person is saying.  Try to see the other person's  side  of  the

disagreement.

    ◆Look the other person in the eyes when you are talking.

    ◆Ask questions to make sure that you understand the other person.

    ◆Repeat the other person's ideas as you understand them.

    ◆Never put anyone down. Saying things like "You've stupid" makes communication difficult. Try to

find a solution that makes the two friends happy. Never decide who is right and who is wrong. Instead ,

help them to find their own " win - win"  solution.  A "win - win" solution allows each of them to feel to

feel good. In this way, their friendship can be continued.
