@Coach: I think it is a tool to help you get detached and not hang on every word and action. You have grown up past that point.

Nooooo -- that's far-too-easy a dodge. What's the tipping point? At what point are Walkaway's words reliable? That has comparatively little to do with one's growth. If what Walkaway says when s/he is trying to hurt Left-Behind is an unreliable guide to Walkaway's "true" feelings, then why is what s/he says when the Walk gets lonely any more reliable?
