So it turns out that learning a visual language mostly on your own is a bit more difficult than I thought it would be. I've been practicing fingerspelling a lot lately, spelling words when I'm listening to music or just walking around my house. I thought I was getting pretty good at it.
A few days ago I went to work and asked one of my coworkers, who knows ASL, to spell something for me. And as soon as she started moving her fingers, I was lost. Oops. As it turns out, signing things on your own and watching someone else sign? Two completely different things.
So I'm going to keep practicing. What I'd really love to do is take an ASL class, but the community college classes already started about a month ago. Guess I'll have to wait until the next semester starts, but in the meantime, I'll just keep trying to learn as much vocabulary and grammar as I can on my own.
