People are social creatures. We are not designed to live solitary lives. We do have varying preferences for how we connect with others. Some people prefer smaller, intimate circles of friends (introverts), while others are drawn to larger groups from which they draw their energy and social rewards (extroverts). Whatever your specific preference, most people seek out their deepest level of connection with just a single partner in whom they powerfully invest deep hopes and dreams about their future lives. (Let me temporarily move past the sad truth of how often people’s choice of that life partner doesn’t last as they’d hoped.)
