When I was younger I would sign in DGS (german) then SEE. I didn't know what it was, I just called it "sign language", then many many years later I met someone else who signed and tried to talk to him he signed so so very fast.
At first I attributed to my sign being very very poor because I never went to Deaf school and never learned the right way, I only learned by watching others and learning on my own. Then I watched and he was asking me for something (if I wanted to sit) and the sign for "sit" was virtually the same but had a little different... the left hand was in the H position where as mine was always in the C (I was taught that C is for chair.
Then later on I noticed at the end of the day he said he was going home. His home sign was ...the right hand in the shape of "more" and he went from the corner of his mouth and drug it to his ear.
My sign for home was the same at the beginning. The "more" shape on the corner of the mouth to emulate "eat" almost, and then the sign for 'sleep'. To indicated "where I eat and sleep". I liked his sign FAR better.
I really wish I had gone to Deaf school, or at least have some Deaf people around that I can converse with.
