I need to warn people before getting into even a brief conversation. Saw some friends outside the cinema and I didn't know where to look because the only place I would've looked was into their eyes. I mainly speak at the ground. Had a talk with a lady in an office today who didn't know there was a boundary, and apparently looked confused at my friend. I must seem very rude. I also think I must look slightly like I'm blind as when I talk to someone it's as if I'm not focusing anywhere, especially not at them.
I missed no physical contact more than no eye contact. It's somehow more comforting.
