I'm not sure I've kept up with the convo - but I'm loving it so thank you - but to pick up on the re-telling piece....
I think that making meaning out of trauma and tragedy is a key piece in PTG. But that's very unlikely to be possible in the immediate aftermath. There's too much shock, pain and confusion. Too much struggle. And who's to say how long the 'immediate aftermath' lasts anyway. It's so individual and there's no time-limit. You can be thrust back into the immediate aftermath after a recovered memory and re-triggering event. So it's not about dates and timelines.
But when it comes to making meaning I think of someone like Rosie Batty. Who took such a horrifying trauma and turned it into a crusade. Not all traumas, and the subsequent actions, are that dramatic and high profile. But many of us will have more personal examples of how we took something truly terrible and found a way to give it meaning.
