How to help non-Buddhists understand a young person's desire to be ordained as a monk?

Many non-Buddhists do not understand the appeal or the benefits of becoming a monk. They may not be able to understand why one would want to live such a simple life, and they may not take the decision seriously. What are some of the "selling points" for ordination (particularly as a young person just over 18) that a non-Buddhist would understand? Are there any organizations or resources for non-Buddhist families or friends of Buddhist monks (aspiring or otherwise)? How can one help a non-Buddhist loved one understand one's desire to be ordained?
