You reconstruct your memories

Because we experience our memories as mini movies that play in our heads we tend think that our memories are stored away as complete little files much the same as a video on your computers hard drive. This, however, is not the case. Every time you think back to your third grade classroom that memory is reconstructed by your mind. This leads to the obvious conclusion that no two recollections are ever the same. In fact, our memories change over time and can influence one another.
