Personally, I'm pretty willing to take folks where they are and with however much they feel like disclosing. I used to dig relentlessly. And as a shrink, I'm very good at it.
But there are many reasons for sharing and not sharing . . . and that's OK. No one shares absolutely all with anyone. Rather impossible given time constraints.
But when an anomaly pops up, sometimes curiosity gets the better of me.
When one considers that people reading this thread take what is said to heart and when one considers that the matter being discussed and taken to heart is something that affects ones eternal salvation, the credibility of the posters is of utmost importance.
If a poster speaks from the heart on a "witness" thread, it is extremely valuable for readers/listeners. However, if a witness is a pretender, it is important to know it (at least it is important for me).
In a psychiatric relationship, it is just the patient and the healer. But in a forum, there are others who are affected by what is said and those listening in attentively but not actively participating exercise an intense "due diligence" in determining whose witness is valuable/credible and whose is not.
