I used to do sign language before I could speak.

I have since forgotten it.

If I tried to relearn it, it would be difficult, because I'm left-handed. You could argue "just mirror right-handers," but some signs are side or direction sensitive.

Did you know ASL is closer to Japanese grammar than English grammar? And that it's based on Old French sign language? This isn't sign language for old French, but rather old French sign language.
