I have no idea what you could do. It is funny, though, people often feel comfortable having conversations around me that they wouldn't have around a sighted person. I can relate to being perceived as a mindless idiot, or perhaps it's that I might not be able to recognize them later on. I do get to hear people say the darndest things, though.

I suppose you could be thankful that people arn't getting angry at you, and taking out their frustrations on you, because you're office mate isn't around when they need him...
