I recently went to an ASL meetup and I do not have a working knowledge of ASL, only half the alphabet and maybe ten signs! At first I felt like a burden but a woman there did help me out a little and taught me colours, drinks and such. When she had to go, another guy there helped me with some vocab. There were other conversations happening alongside us too amongst other people.
Now I'm not so sure how I feel about going to a meetup... I really really liked going and I had a lot of fun, but from what you said, how terrible is it that I am going and don't know any sign? I am indeed too cheap to pay for classes. I am unemployed and staying in a town for the summer that I have never been in. I have only a little pocket money. But I still want to learn sign!
