Hmm. I'm pretty certain I don't want someone to share the story with in order to have them clarify what I thought of the events. I travelled with idolatrie and sometimes we're telling the stories and she's got a different spin on something, and I don't hesitate to correct her. I don't doubt my own memories or what actually happened.
I enjoy telling stories, generally. I find it entertaining, for both myself and other people. I like sharing experiences with people because then they also become a source of memory for me. Like once, walking down a street with the sun shining, I was suddenly reminded of some happy things that took place around the same time the year before, because of the weather. And I could call someone who went on that trip with me to talk to them about it, which made it nice, because I like that shared sense of remembrance.
I'm definitely keeping the 'playing the role of teacher' thing in mind, but different teachers, valuing different things, would probably affect different personas.
