Have you learnt sign language?

I learned as a baby (which actually became an issue since I then decided speaking wasn't necessary until I was around four lol). But my cousin started learning in high school. The basics are really easy to pick up. So you CAN communicate with it. But the sentence structure is different with ASL, so it can be harder to figure out longer sentances that you can use In conversation. As just a form of communication, though, it's really easy.
