      How do you repair a broken friendship?I'll give you several tips below.

      To begin with,a real friend is a treasure (财富).You don't throw a friend away because your feelings got hurt or you are unwilling to discuss a misunderstanding.Don't let senselss things destroy your friendship.To me,if it's worth the fight,it is worth the sacrifice (牺牲).If you can't sacrifice to keep the friendship,

then maybe it isn't true friendship.

      Be willing to apologize even if the problem isn't your fault.The friendship is larger than who is at fault.If you can heal the friendship with an apology,then do so.Don't wait for your friends to realize how wrong

they are,or even to admit their share of guilt.Go to them.Make the first move.Raise the white flag first.

However you want to look at it,be willing to do what it may take to heal the relationship.Many friendships stay wounded or destroyed because both waited for the other to make the first move and neither did.

      Remind each other that the friendship is more important.A simple reminder of how special the

friendship is will go a long way to soften a hard heart.Be willing to take the higher ground.I have a policy in my marriage that if there is a disagreement in values,we always take the higher one.If you can't come up to your friend's level,you will begin to estrange him.I feel that the friendship is more important than my

personal position.The higher ground is always safer anyway.

     When repairing a friendship you must remember that together you can complete much more than either can separately.A friendship is full of synergy (协同作用).
