past present future

when I look back at life I view it as a story:

events seem quickly linked, and the insignificant drops from the plot. The moment often seems mundane, and only in the future will it gain meaning or a role in the story.

someone recently told me that we remember terrible things fondly because we are subconsciously pleased for remembering details. 

While this might be true, i choose to believe we can accept the sometimes terrible past as a comfort because from present perspective it seems to only be a chapter in a story which leads to the present.
