Awww, I bet that's like delightful that your alter maybe aware. I'd start learning sign language because it sounds like an attempt to connect.

I wonder how would you set that up journal like? Video? Maybe she can write...that makes sense. I'd teach her how to write.

I'd sign into a mirror so that she can see it face on. She might help you learn it faster too! This could be so fun.

I used to be around deaf crowd but never learned it, but it's not really that hard since their are single signs that means whole words. Have fun!
