These categories aren’t necessarily permanent, fixed, or as clear-cut as we might want them to be—and that’s OK, says Melewski. For instance, he explains that an acquaintance can become a close friend or a work colleague who starts off as a casual friend can become a best friend with time. “On the other hand, knowing someone from childhood doesn’t always guarantee an intimate connection. Childhood friends need more than history; they require mutual support and effort.”
Sometimes you meet someone new and just know you’re going to be close friends. Other times, it takes longer to get to know someone until you (or they) feel comfortable enough to put your walls down. But once you find your people, life generally tends to feel a little fuller. Friendships, how they happen, and how intense they are will vary for everybody. Perhaps you’re still close with your childhood friends or feel happiest when in large, diverse groups. You might feel fulfilled with just a handful of deep friendships, or maybe you’re a social butterfly whose calendar is never empty. Whatever friendship style feels right for you, there are several benefits that you could experience as a result of these connections.
