Thanks for your message, I’m really glad to hear you found aspects of Charlotte character you could relate to.
To answer your question, I did not set out to do so consciously, but when writing Charlotte I had an idea of what characteristics I wanted to give her and how I wanted her to be different from her peers in the way she perceives and interacts with the world – specifically in the ways you mention.
I suppose I always look at the characters through a lens of how they would be perceived in that time-period in that world.
Characters in Segunda just view Charlotte as ‘different’ (some even think her stupid, though they are wrong), but I can certainly see a more modern mindset seeing her characteristics as indicative of neurodivergence. ^_^
