One can never truly recapture the past in one's memory. When we look back on our memories, it's not like a tape recording. We view those memories from an adjusted perspective; the lens of newly acquired mental models in the interim.
The only way to truly record memories as they happen is with a diary, since transcribing the experience to text illustrates the mindset of the writer at the time.
What is a mental model? Mental models are our way of deconstructing the world.
