To me, I interpret making a list like this as something someone would do who isn't au fait for social interactions, and is definitely beyond the actions of a typical introvert. Again, suggestive of ASD.It was an old video, maybe a year or two ago? Some sort of notebook/bujo video where she said to basically keep track of your friends and what they do for you.
I remember the way she explained it was so.. clinical and detached. She legit said to make a list of it.
