Thank you for sharing the story with us. It is too bad and too sad for the girl including you at the time back then that you and the girl were not comfortable being deaf. That is the reason why many late deafened and also deaf adults who were born deaf are ashamed. Many hearing people think being deaf is really bad and sign language is also bad for the deaf people, but not bad to the hearing people. This is what irk me so much that it is not fair for us to tie our hands and not use the ASL and be comfortable being deaf. That is why we need to speak up to teach the hearing people about our deaf rights and our deaf perspectives.
I hope your story will teach hearing parents and hearing people realize that they can not make the deaf hear like hearing aids or CIs. They don't work like that way. We have been trying to tell the hearing people for a very long time (over 100 years). Now I see there is no change unless something is done to change about this same old crap making the hearing people think we can hear with the hearing aids, and now CIs. That is their dream world. Yes, it is sad that the late deafened and some born deaf can not be comfortable because of the hearing mentality.
