       No one is an island. We share the world with parents, friends, teachers and classmates. Most of the

time, we get on well with each other. But we sometimes disagree too.  Here are some tips for solving

problems:

       Sharing: Say what is troubling you. If you understand each other it's easier to solve the problem.

       Take turns: Let the other person have his or her own way for a while.  Sometimes it works well.

       Take turns: Let the other person have his or her own way for a while.  Sometimes it works well.

       Flip (抛) a coin: If you both agree, sometimes chance is the best idea. You could flip a coin, or

play "rock, paper, scissors" (石头剪子布).  It's fair and neither of you has anything to complain about.

can suggest the other person do the same thing. It's always best to try to work together.
