This keeps them alive and rolling into oblivion IMO...
It's how they remember things.
Memory is, if nothing else, changeable.
Ever look back at a holiday and think how great it was, but you vauguely remember fussing about silly things, but the memory makes you feel good now?
Anybody who tells you that you can't change the past hasn't really thought about what they are actually saying, what they actually do with their own past, or they are lying for some unknown reason.
I guarantee that if you spend all of your time ruminating on every negative emotion you have ever felt, you will only remember a past of crap and pain.
Made a gratitude list lately?
