Well that's not a nice way to think. I feel like it's important for everyone to at lead to the basic alphabet in their sign language so people can at least communicate! It's really easy too!
@Saurna, yes!! Its important to have patience and smiple skills! Its not like they can help it either! People shouldnt be mad about what they cant control and just learn to adapt. Like I learnt the basic auslan alphabet in a few days surely they can learn
