It's certainly a very deep topic. When it comes to personal memory, I've learned people's perceptions of events and experiences can be quite different based on their own values and perceptions. This makes the telling of events, not just historical, but even current become somewhat subjective. We see this in our news cycles today where events can happen, yet the interpretations of those events can be so vastly different. This makes the search for truth seem rather difficult at times. It also makes the retelling of history sometimes hazy.
When I'm researching something, either historical or current, I like to check out different sources and see if there are underlying or common themes. It helps me to set aside the "opinion" and look more for the facts.
True indeed. I suppose we just have to be more careful telling other what we think we remember.
