what is the onion analogy? explain using: beginning, early, developing, later
beginning stage: disclose lots of info (broad) but it is low-risk and superficial (no depth)
early stage: must be careful of sharing too much info as revealing too much can threaten a relationship
developing stages: self-disclosure increases in depth (removing layers of the onion) and the breadth of acceptable topics increases
later stage: reveal high-risk intimate info at the core of the onion, e.g. painful memories, strong beliefs, secrets
