     Do you get angry when your friends sing loudly while you are trying to work or when your best

friend does not wait for you after school?

     If you do, you need to take control of your feelings. Getting angry with others can cause you to

lose friends.

    Gary Egeberg, an American high school teacher, has written My Feelings Are Like Wild Animals

to help you control your feelings. It tells how to stay cool when bad things happen.

The book says that getting angry only makes problems worse. It can never make them better.

"Getting angry is not a natural way to act," the book says. It is just a bad habit, like smoking.

The book says you can control your anger easily … all you have to do is to tell yourself not to be angry.

The book gives many tips to help you if you get angry easily. Here are the top three.

else. Try to laugh.
