Forming and maintaining
Forming and maintaining friendships often requires time and effort. To form a friendship requires around 20 to 60 hours of interacting in the first weeks after meeting, while forming a close friendship can take more than hundred hours.
Friendships are foremost formed by choice, typically on the basis that the parties involved admire each other and enjoy commonality and socializing.
Given that friendships provide people with many mental, social, and health benefits, people should want to associate with and form lasting relationships with people who can provide the benefits they need. Thus, people have specific friendship preferences for the types of behaviors and traits that are associated with these benefits. Recent work on friendship preferences shows that while there is much overlap between men and women for the traits they prefer in close same-gender friends (e.g., being prioritized over other friends, friends with varied knowledge/skills), there are some differences: women compared to men had greater preference for emotional support, emotional disclosure, and emotional reassurance, while men had greater preference for friends that offer opportunities for accruing status that boosts their reputation, and that will provide physical aid.
Most people underestimate how much other people like them. The liking gap can make it difficult to form friendships.
According to communications professor Jeffery Hall, most friendships involve tacitly agreed-upon expectations in six different areas:
Positive regard
The friends genuinely like each other, and are not merely pretending to like each other for the purpose of social climbing or some other desired benefit.
Self-disclosure
The friends feel that they can discuss topics of deep personal significance.
Instrumental aid
The friends help each other in practical ways. For example, a friend might drive another friend to the airport.
Similarity
The friends have similar worldviews. For example, they might have the same culture, class, religion, or life experiences.
Enjoyment
The friends believe that it is fun and easy to spend time together.
Agency
The friends have valuable information, skills, or resources that they can share with each other. For example, a friend with business connections might know when a desirable job will be available, or a wealthy friend might pay for an expensive experience.
Not all relationships have the same balance of each area. For example, women may prefer friendships that emphasize genuine positive regard and deeper self-disclosure, and men may prefer friendships with a little more agency.
