Two people who have committed to building their future together must have at least a few things in common, and their level of social interaction is generally one of them. When one person in the relationship is very outgoing and the other is not, it can cause friction between the pair. A person who likes to throw parties is going to tend to plan them, but their spouse hiding in a backroom while company is present can become an issue.
Being able to compromise is an important part of keeping a relationship healthy, so this couple must find a way to level out their socialization skills. If they do not, their relationship will ultimately dissolve. Learning how to balance a need to entertain with a need for solitude is their goal, and each of them must be willing to participate wholeheartedly in the desires of their partner so they can form a lasting bond.
