Because both parties know how to work hard, and have a good head for getting ahead in the world, this is a very good combination, not only in romance, but also in business. This is a couple that knows how to build for the future and develop a very secure relationship. Like in any other number combination, dangers do exist, and feelings of frustration can overshadow the love and respect that is the foundation of this relationship, but overall this is an excellent number pairing.
