Can all deaf people read & write!, bit of an odd question & almost insulting to some as basic education or the lack of it, has no connection to deafness in my opinion.
However in saying that, I never learnt to read & write till I was in my early 20's, I never actually went to school & had very little education, many years I struggled with work avoiding any kind of forms & paperwork, mainly passing it on to work friends & family to deal with, I managed around 3 years without the basic reading & writing ability, amazing I know.
Wasn't till I started working for a building firm that paperwork really came into play which for me was unavoidable, tooling lists, written work orders for the day which were given to me on my first day, I really panicked I just couldn't understand any of it & not having anyone there to help me, really made me realize how stupid I was.
So I admitted to the foreman I couldn't read & write, needless to say I was dismissed on the spot, boy that really hurt to go home knowing I'd made a complete fool of myself in front of that work team.
But that totally turned it around for me, I was just kidding myself to think I could get through life without that education, so I started studying in my local library & the help of my sister who was my saviour who took time off her own work to help & support me.
So the question posed on this thread is pretty much redundant, Deafness bares no relation to education.
