Stories and memories are important. 

That is why so many of us keep, or have kept,  journals or diaries.

Recall a time in your life when you shared something significant with someone else.  Each write a short story about it.   Compare your stories. 

Be curious about the inconsistencies, they will be there.  Unless something very specific was written down for you to refer to, you may want to get comfortable with the changing story.  This story sharing is a way of communicate in the present moment. 

The present moment is the only reliable story.  As many wise seers have said, there is power in the present moment.
