I’m not sure if this is going to sound strange, but I’m so accustomed to the voices of different kinds of people that my mind at this point just registers the many different accents as different voices within one accent (as in my mind doesn’t say “oh that’s another accent” anymore, it doesn’t register it) and I actually miss being able to appreciate peoples’ accents as accents, which sucks when for example you’re attracted to them.
Be autistic and you probably won’t get used to accents…lol. One of my traits is the inability to form habits or “get used to” things in general.
