You and your generation idealize freedom and adventure more than the stability of a single long-term relationship. You are much more likely to enjoy a series of relationships, often with people who are radically different from you -- perhaps people from another country or a completely different culture. You appreciate the exposure to habits and beliefs that diverge from your own, because in this way you learn deeply about people from different places on earth.
In your eyes, there is no better way to expand your consciousness than to do it through another person's eyes. Relationships are roads to learning for you; and there are many roads to learning, are there not?
