I am thirty-seven years old and I still think about what happened at Jordan Muñoz's birthday party in 1999.

I won't describe it in detail. It involves something I said in front of people who laughed, and the specific quality of that laugh, which was not friendly. I was thirteen. The people who laughed have, presumably, forgotten. I have not.

I understand the neuroscience of this. The adolescent brain is particularly sensitive to social rejection because belonging was once a survival mechanism. The encoding is disproportionate. I know, as an adult, that the event was small. I know this as a cognitive fact while simultaneously feeling it as a present wound. The knowledge does not dissolve the feeling. The feeling does not care about the knowledge.

What I'm interested in is the specificity of the memory. I don't remember most of seventh grade with any clarity. I remember that moment with HD precision - the wallpaper, the music that was playing, the shirt Jordan was wearing. The brain preserved the trauma in extremely high resolution while letting the context blur. I have better recall of my worst moments than my best ones. The archive is curated toward injury.

I've tested this. I try to remember a good day from that year. I can generate approximate feelings but very few sensory specifics. I try to remember the party and I'm back in the room immediately, fully embodied, full sound and color.

Is this the self's form of vigilance? A way of staying ready for the next version of that laugh? If so, it seems inefficient.

What does your memory preserve in high resolution? Is it what you would choose?
