How the Americans view love

An old song says that " love makes the world go around" If you watch Americans on Valentine's Day, you can believe it. The whole country breaks out with little red hearts. Lovestruck people give cards, flowers and candy to their sweethearts.

The American concept of love and romance begins with dating. Young people date in several ways. At first they might have group dates with several boys and girls together. Later, they start going on single date - just one boy and one girl.

When two couples go out together, it's called double dating. A friend might even arrange a blind date for you with someone you don't know who your partner will be until the time of the date.

American young people see a date as a time just to have fun. They don't always have a romantic interest in mind. Someone may go out with one person this week, and another the next. After a while, a boy and a girl may decide they want to go steady. This means they think of each other as boyfriend and girlfriend. It also means they don't want to date anyone else. Romance is beginning to bloom.

Romance love is very much a part of American culture. Movies, TV shows and books in America all picture people falling in love. Actually, people all over the world search for happiness in a loving relationship. Maybe love does make the world go around.
