    American schools do not have separate classes for boys and girls. If boys want to cook or to sew, they can learn these things in classes that are no longer just for girls. If girls want to repair cars, they can now learn this in school. Most students like to have boys and girls on the same baseball team.

Many boys and girls dress alike in school. They wear blue jeans and sport shirts. Some have long hair and some have short hair. Sometimes a boy has longer hair than a girl.

Even the language is different. Students learn to say fire fighter instead of fireman, police officer instead of policeman, and letter carrier instead of mailman. A person does not need to be a man to fight a fire or to deliver the mail.

Most people think that these changes are great. They give all people an equal chance to be happy and to do what they want to do with their lives. Fathers like to tell their sons that they can grow up to be president. Today, mothers can tell the same things to their daughters.
