Yes, exactly, but because I now know my brain/memory works like this I just don't expect the index card thing to work any more. I externalise things like that with things like Notes on my phone and Google Calendar which syncs automatically everywhere.
I used to get very frustrated because other people (e.g. parents, teachers, peers) have the expectation that the index card thing is a given and everybody has a system like that, so I assumed that I should as well, except I lacked the visual image of that, nor the knowledge that most people don't have the tendril thing going on (well, I'm sure they must on some level, but probably not as much as it does to people with ADHD).
Everything is tied together using the string. So if I follow the right string eventually I will find something again, and most things are linked to several different strings, but if I just try to look at it all at once it would look like a stringy mess and you can't make out what connection goes where.
I was just thinking about this metaphor/explanation after I wrote this post and went to the loo and got myself a snack. I was trying to be observant, so I noticed that while I was sat on the loo I looked at the cover of DS2's book which was on the floor and has lots of different pictures on it. There was a tiger and I thought OK, I wonder what thought spiral would come from the tiger, only to notice that nothing did, because at that point I was thinking about the post I'd made and some of the banana-inspired images or feelings, and some other post I'd read earlier on MN and this follow up. And maybe also because I've seen that tiger loads of times before. So I saw the tiger, but I didn't really register the tiger. (And if I was neurotypical I'd probably think what is that book doing on the toilet floor, and take it to tidy it away, but I didn't think or do that). I was still on the same topic while I was getting something to eat, and so while I was able to focus on what I went in to do, I could not tell you how close we are to running out of milk or what state the kitchen is in generally, although I think it's probably in need of a tidy up. I'd taken some plates out from the living room before I left the room, but I now have no memory of placing them down and I don't even know if I put them in the kitchen, though it's quite likely that I did.
It was quite interesting just to observe because I think most people when they entered a messy kitchen would register the state of the kitchen, and that would be a reminder to clean it, either immediately or just sort of adding an exclamation mark to a mental to-do list or so on. And sometimes when I enter a messy room, I have this kind of thought, but more often I don't really "see" anything except what I've actively gone in to do. But another time (like when I was going to the job interview) I see something random like some bananas painted on a building and it starts a whole thought spiral going.
Anyway by the time I got back I decided this was boring and moved on to something else, so I don't know why I've decided to post it all now
