This would be a great thread for a Larian person to post a comment. I suspect they might have a "no-post" company policy, but I hope at least a few of them are lurking here.
There I was at the Rochester Institute of Technology (New York, USA), walking down a dimly lit basement corridor and just about to turn a corner, when suddenly a group of five or six girls rounded the same corner from the opposite direction. They were talking in sign language, and when we nearly collided, they signed even more excitedly and with their hands held high over their heads. We all laughed and went on our way. I later learned that raising hands high is the sign-language equivalent of "shouting". I wonder if that is common worldwide?
