The reason it probably has so much staying power is that you are thinking this is a missed opportunity for something you are lacking in life. Go get the thing you are lacking qnd you will laugh when you look back on this situation.
I'm not thinking about it as intently as you portrayed here. It's merely a nice summer memory. I'm trying to decipher why it's a nice memory because it's now feeling like she did me a favour by approaching me, at the particular time she did, and now there is a nice memory.
I think that something happened in the outdoor gym/bike trail that put me off balance emotionally. I saw a older guy and hot girl sitting together on a chair adjacent to mine and just felt bad that stuff like that never happens to me. It appeared they just met from online dating or something. I was sitting there taking a rest from the trail ride and then I just couldn't take sitting near those two people, and just left my bike and bag and started working-out (as other people were), in this outdoor gym. They had pull-up bars, tricep, bi-cept, all sorts of bars and that got my mind off of that. I then rode back on the trail after the workout but noticed I left my stuff on the chair and feel that lapse of judgment was due to feeling off balance emotionally because of incelness.
It was during this particular state of mind I met this girl at the bank which basically reset my whole mind from the previous bad feeling. I went from feeling bad to feeling great after seeing her like magic.
This is why I've said on previous posts that I feel there was some emotional or mental imbalance that was tornadic, that came out of that particular trail ride/outdoor gym and that "couple", and, if there are "laws of attraction" in the universe, it's quite possible I could have inadvertently attracted her into my reality in order to balance myself out. For this to happen, there would have to be something tornadic to the point of a mild shock or disturbance, it can't just be a low-grade comfortable state of incelness but a highly intense incel shock.
The fact it's a nice memory means that something "good" happened with me in that whole interaction.
In terms of getting the thing that I'm lacking, if I'm "incel", then by definition, it's unfair to suggest to get the thing that I'm lacking, or I would not be incel/nearcel in the first place. But, I'll spare that discussion for this thread. Maybe this is an "incel-thing", or "incel-memory", or "incel-fantasy".... maybe it's that then.
