I am taking a beginner ASL course at a local Deaf community centre, and I am really enjoying it.

I also have autism, and am very "stiff" physically, for lack of a better word. It has become clear to me that I am going to have (/already having...) a hard time with facial grammar. Not with understanding it, or with remembering which expression means what, but with physically doing it. Obviously it is a major problem to be using a language without proper grammar.

My question is, would it be weird or rude of me to tell my teacher this? Both that I have autism and might struggle with being expressive, and that I understand how vital it is to ASL and will be working hard on improving? It is a silent class and I am really worried that I will get stuck on a correction and not be able to explain myself, or that she will think I don't understand why it's necessary, which is why I want to let her know. But I also don't want to sound like I'm making excuses, and I don't know if it would come across that way! I can't trust myself on what's rude and what's not because of the social disability thing, and it being sort of cross cultural makes it even harder.

Thank you very much!
