-Xargon Guurn says: While talking is a very useful tool when roleplaying, you also have to be able to express yourself in other fashions, eh?
-Xargon Guurn says: Facial expressions for example.
-Xargon grins.
-Xargon Guurn says: Or even more complicated actions.
-Xargon kicks at the ground, stirring up some dust.
