The eyes are the window to the soul -- or is it that the eyes are the window to intimacy? When you gaze into the eyes of your partner from across the table, you're doing more than just being attentive in the conversation: You're being intimate.
Eye contact is a key component to how we socialize with other people, and it's one of the most important pieces of creating an intimate relationship, romantic or otherwise. Known as face-to-face, eye-to-eye communication is a subtle, non-verbal way of making yourself vulnerable to another person.
Eye contact shows trust and emotional openness, and it also increases our feeling of being understood by another person.
