To be fair I had no idea everyone wasn't like this until partway through secondary school.

Was learning another language and some of the class had spent a good amount of time overseas immersed in that language and came back saying their thoughts sometimes switched between languages.

To my confusion I asked how their thoughts had a voice which confused everyone else who didn't understand how thoughts couldn't have a voice

There's always thought, but for me it's more like abstract data than an internal monologue.

For me personally I don't think I'm completely on that side of the spectrum but I did find it frustrating that I found it hard to engage in live conversation as it took me a while to convert thoughts to language.

This did lead to many people thinking me simple in my younger years.

I eventually compensated by memorising tons of scripts that I could use to engage in conversation which I use in day-to-day conversation and use it to buy time while I work out how to convert unscripted thoughts into language
