I explode less often now than I used to (and then, it was just once in a blue moon), and it's usually when my sense of justice has been very violated by someone I thought I could trust not to do whatever they did.
The List....yes. It's not really because I have an ongoing tally, it's just that as my brain is trying desperately to make sense of how someone could act the way they did, the connection making part of my brains explodes in an intricate spiderweb of instances that support whatever theory ends up making the most sense. It's insane, the amount of emotional info that bubbles to the surface from the past and gets connected and categorized during the short couple of hours that I'm angry. It leaves me exhausted. I tend to sound like a conspiracy theorist while I'm babbling on like an enraged seer, probing motives that I usually have the decency to leave alone, making predictions about the future, hurling accusations that have a good bit of truth and a great lot of fear. It's mostly because my emotions have been thrown off-kilter and my J demands an explaination, and I don't have enough time to cull out the more outrageous conclusions like I normally do.
It's like an explosion of slightly off-balanced intuition. My spouse (the one who usually catches most of my anger, just because he's one of the few I trust to that level) has learned to don a fire-proof jacket and take notes. Even though a lot of it is angry/fearful babble, there's usually a good deal of useful insight mixed in as well.
I've gotten better at apologizing over the years.
