iiaat that when i ask mom to get me something from the store (chocolate, for example) but the store doesn't stock the brand i want and she brings something similar instead, i feel like i'd rather have nothing because i wanted That One Brand? i always thought i was being ungrateful but now i've discovered i might be autistic and it crossed my mind that being this picky might be due to that. :/
Yep! That would be an autism thing. This would relate to internal rules. You have to have Brand because that is the Right brand and other brands are Wrong.
