Learning Amercian Sign Language

I have just gotten a new job working in a group home, and a lot of the women who live there use amercian sign language. It is a condition of my job that I learn a certain number of words in my first couple months working there. I have been trying hard to learn and picking up quite a few words from the women at work. I have been practicing at home too, and now my son is actually picking up some as well, which is a good side benefit. He thinks it is pretty cool to be able to talk in sign language.
