It was baffling at first, until I remembered something rather similar. What other institution allows for a nearly-anonymous cathartic purging of oneself, where the identities of both parties is secret and unknown?
No, not therapy--you know the identity of your therapist, and she or he knows yours. In fact, the opening of therapy is usually a "get to know you" session.
What occurred to me was how similar Internet relationships can be to the Catholic practice of confession.
I'll have to think about this more, but now that my mind has been open to this possibility, I'd like to see where the idea takes me.
Be seeing you!
