I'm just curious as I have started to learn from Greek sign language. I am on the board for an organization in my area and we were going to have a find language training in British find language as well. I am visually impaired and I don't have enough vision to see videos on YouTube with signing so I just have to learn it hand over hand. When I speak with a deaf person person I can fine, but I have to feel what they are signing. Same thing with my deaf blind friends, we just fine in each other's hands.
In Greece, I will learn facial expressions as well. I have never thought how important this is, and I don't know how we're going to go about doing this since I have no idea what other people's facial expressions look like. But I really do want to learn more sign language though. For those who have learned How long did it take you?
