But in order to let that pain go, in order to remove this person from the place of power they have occupied for so long, you must let everything go. Perhaps in a very distant future, you will be able to pick and choose the memories you want to keep, but for a very long time, one memory will always bleed into another. You cannot simply think about the time the two of you sat on the beach for an entire night, talking about your childhood, drinking the second-least-expensive wine you could find in the store. Because when you allow yourself to think about that, it will remind you of them as a whole, and will lead into all of the terrible things that happened after that night — not the least of which being their eventual departure. They exist within us as whole people, stories with beginnings and endings, and in order to let go of them we cannot choose the things we want to isolate for nostalgia.
