I am quite shy when it come to social interaction, but only because as a deaf person with low vision, I am not entirely sure of a person's body language. Usually I am the one that speak first, but only after I can pick up the vibes and see if I am comfortable with the people. I have been told I can appear to be aspie (slang for Asperger's) from time to time. However I am told by the CNIB that is quite common for blind people to appear that way if they didn't get training on how to "appear normal" ie. smiling and making eye contacts (even if they can't see.)
I get a lot of questions if I am from Germany due to my flatten vowels or if I am Dutch or French because I use a lot of the "guttural r" yet I can't roll my r at the front of my mouth to save my life. 
I even get people that ask if I am Irish because of the loanwords I use from the Newfoundlanders and Scottish from my hometown. 
But most people are surprised to find out that I am deaf, and that I don't even follow what they are saying 50% of the time... or that I can't even lipread them that well. My excuse was that people's gestures are predictable and usually everyone have a similar way of speaking. So when they do find out that I am deaf they usually go "Oh! I didn't know you were deaf!" "Do you understand sign language?" "You tricked me" and so on. Of course, then people will start over-empathizing their mouth movements if I ask them to repeat, which makes it even harder to lipread. :roll:
