Disclosure Reciprocity: This is the tendency for one person's openness in self-disclosure to match that of a conversational partner. It's like a game of tennis - if one player serves (discloses), the other player returns the serve (reciprocates).
Social Penetration Theory: This theory suggests that as relationships develop, communication moves from relatively shallow, non-personal layers to deeper, more personal ones. It's similar to diving into a pool - at first you're just dipping your toes in the shallow end (sharing basic info), but eventually you may dive into the deep end (sharing intimate details).
Vulnerability: This refers to exposing oneself emotionally by sharing sensitive information through self-disclosure. It’s like standing in front of someone with no armor on – it can feel risky because they could potentially hurt you, but it also allows for greater connection and understanding.
