“But when an introvert is hanging out with a friend, sharing reflections, he is in his element. The conversation is “mind to mind” rather than “mouth to mouth.” Extroverts share ideas too, but the ideas are secondary to the interaction and develop between the two people as they talk. The focal point is external. For introverts, the focal point is internal, with each participant bringing the other inside and working things out there. A good conversation leaves an introvert feeling more connected, but also personally richer.”
