[Blindtlk] Other "wrong" assumptions;Learning body language

[Gerardo Corripio]

Robert's message about false assumptions in the workplace reminded me of the 
following incident:
The other day while attending a dinner with some coleagues one of them asked 
"Are you able to eat on your own"? comment which angered me, though I know 
the sighted person asked me with good intention it still made me a bit angry 
to the point that I know still lots of work needs to be done (especially in 
countries where the NFB isn't well-known or even heard of); this is why I 
really enjoy the list; ai always learn a lot from you guys.
This brings me to another question especially for those of you blind from 
birth: How did you guys learn to use body language? I sometimes get to 
thinking that aside from integrating more with the sighted world, it saves 
our mouths from talking, especially while eating or doing other things that 
at that moment doesn't permit us to speak.
also, when saying no (shake of the head) is it from side to side by moving 
the head from shoulder to shoulder or moving the head clockwise or 
counterclockwise?
also what does srugging the shoulder signify? As you see we blind from birth 
lose a lot of things by not being able to see. And when I first introduced 
myself the RP I took it to mean Retinopathy of Prematurity like in spanish, 
thus didn't think to clarify the concept.
