Not just one best friend
There is a balance between depth and width in friendship.
Today, the term is still widely used. But most of us don’t naturally fall into friend pairs. Seeking them out, then, can lead to hurt—if we choose one friend over another, if the best-friend designation isn’t reciprocated, or if we don’t have a closest friend but feel that we should. For those who do have one, prioritizing them could mean turning away from other, potentially fruitful friendships. And relying on one person for all of your emotional needs creates a lot of pressure: No one is available to be a great friend 100 percent of the time.
