Sometimes I wonder, if our memory could be like a DVD rental shop. You’d get to choose what to watch, what to skip, what to “probably later”. Or it could be like a chest of drawers, each with its own key. You could leave the pleasant ones permanently open, while locking up the events you never ever want to recall and chuck out the keys.
Reminds me of the first part of “Hannibal Rising” and how Hannibal Lecter could compartmentalise his memories into separate “rooms”, each attached with a different type of music. Scary books, by the way. Spine-chillingly gory but grippingly good.
