Several people in comments raised the issue of secret vs. private wondering about the difference and how that plays out in therapy.
While the dictionary does not make a clear distinction between the two, in practice they are different. We might start with this:
Privacy is the state of being unobserved; changing clothes for example -- that which I keep private, I am merely withholding from public view. Private matters are those traits, truths, beliefs, and ideas about ourselves that we keep to ourselves. They might include our fantasies and daydreams, feelings about the way the world works, and spiritual beliefs. Private matters, when revealed either accidentally or purposefully, give another person some insight into the revealer.
Secrecy is the act of keeping things hidden -- that which is secret goes beyond merely private into hidden. While secrecy spills into privacy, not all privacy is secrecy. Secrecy stems from deliberately keeping something from others out of a fear. Secrets consist of information that has potentially negative impact on someone else-emotionally, physically, or financially. The keeper of secrets believes that if they are revealed either accidentally or purposefully, the revelation may cause harm to the secret-keeper and those around him or her.
