I think we all build narratives in our head as a means of protecting ourselves - from our own or others behaviors. For me, this is the primary reason for the 'rewriting' of history (along with the cherry picking of events and the perception bias).
For example, "I have met my soulmate and my M is stopping me from being with them" (narrative), "I am sleeping with someone who is not my wife and I am not going to stop" (behavior), "You make me unhappy" (narrative) ... "I am walking out of my M" (behavior). We, the LBS, create own narratives too.
Narratives protect, but also, if left untethered, stop us from taking responsibility for our actions.
I am not sure I added to this chain of posts because I think Steve was trying to make a different point re words are cheap and that it is the actions that matter (and he is right, it is our actions that define us) ... but I have been thinking a lot about our internal narratives and how it feeds our behavior. There is a part of me that ignores the problems in our M (narrative) which stops me from letting go (behavior).
