only once i met deaf people (they had also some mental issues), it was a student's job, cleaning a day taking care centre, the deaf people were the only one that stayed when the others went on a journey, cause they had to 'ask' for it, the deaf didn't understand and the staff didn't do a real effort in explaining either. so they were seated and watched me cleaning, they laughed with me, so i danced with the vacuumcleaner as a kind of performance, and i got an applause. i felt like we had a very good time.
i am very visual and i appreciate people that can't speak, but never came across any deaf people.
(a lot of people in my family don't hear very well, so i do know how to speak very loud and recognise it when people haven't heard what you say, like they'll say yes without having heard the question, this makes it a little akward if you haven't noticed what it 's the matter, but from the moment you realise it, it's ok)
