There are still some societies today that believe arranged marriages are for the best. This alleviates the need for dating, and having young people make the mistake of choosing the wrong person. Many young people in this type of society date casually. This is especially true when they travel to societies that are very different when it comes to marriage arrangements. Some are honest enough to let their dates know that a long term relationship is not possible. Other people simply say nothing and let their dates assume whatever they wish.
There are advantages to arranged marriages, but there are some disadvantages as well. People that date casually until their marriage may fall in love with a person they are dating. When it comes time to marry, they will have to end their relationship. This hurts both people, especially if their partner never knew there was already a promise of marriage to someone else.
