“A friend who is there for you when you’re in need is definitely a friend.” Far clunkier, I know, but I promised you science, not sound bites. And that does clarify what we all want. Be there for me when I need you. The world may be selfish and competitive, but you and I do not have to be. Maybe you can or can’t help with “deeds,” but I’m not just looking for transactional gain: most of all I’m looking for “another self” to help me shoulder the burden of life.
