Boys and dating normal ages
Before the war, "going steady" was a stage young people took only if they were seriously on the path to marriage; however, after the war, the phrase was used more loosely.It no longer signaled that the couple was marriageable and ready to commit (Bailey 49).
Then again, few other countries have the same social conditions as America.
Dating essentially replaced the practice of calling which was the primary way of courtship before the mid-1920's.
When a man "calls" upon a woman, he usually shows up at her house during an "at home" session and presents his card to the maid who then gives it to the young lady.
So they initial shyness of young couple can be eased away by the presence of other company, especially if the double date was a "set-up" or a blind date for one couple.
After double dating, you would naturally move onto single dating.But because the lower classes were not so well-endowed so that they own pianos or even parlors, they started their own form of "courtship" which soon became known as dating.
