Robin Dunbar: A Hero of Friendship Studies

Robin Dunbar is a professor of evolutionary psychology at Oxford University. He says you can have up to five key relationships in your life. To sustain friendships at that level requires time, energy and thinking about. And we simply cannot do that for every single person in our life. There might be a place for those people in my life, but I need to pay more careful attention to how that leaves me feeling because it probably leaves them feeling like that too.
