“We need to catch up soon!”
In the hierarchy of relationships, friendships are at the bottom. Romantic partners, parents, children—all these come first.
This is true in life, and in science, where relationship research tends to focus on couples and families. When Emily Langan, an associate professor of communication at Wheaton College goes to conferences for the International Association of Relationship Researchers, she says, “friendship is the smallest cluster there. Sometimes it’s a panel, if that.”
Friendships are unique relationships because unlike family relationships, we choose to enter into them. And unlike other voluntary bonds, like marriages and romantic relationships, they lack a formal structure. You wouldn’t go months without speaking to or seeing your significant other (hopefully), but you might go that long without contacting a friend.
