It's Okay, I have some accounts over there (not with this name) and people keeping mistaking myself as Japanese native, since I admire them, I feel it as a compliment.
About relatives, no as far I know. My family is pretty nuclear, I have my parents and my brother and sister, I don't know much of anyone, I have a friend who lives there, he don't know much of my Aspie condition, but the part of he know said that "since you don't have the urge to do everything in front of others you can be pretty successful" Not sure if its really true.
But thank you so much, I'm studying Japanese by myself by 3 months (I'm 22 now not too old to dream that right?), and seems like it's working, usually Japanese language have stuff like you write hypocrisy as "false virtue" adult as "big person" and to numerous examples, and this is making me feel really confident of my reading, I can detect patterns on almost everything, so Kanji at all don't scare me. Some stuff on Language ofc is harder, but I think is due the lack of exposition.
I believe language is one of my talents (at least English, I recall most of schoolmates went to actual english schools and don't seem really proficient even at school tests, some even failed at school)
If you mind to share some your experiences I would love to know.
