Grey Roleplay

I started using the term 'Grey Roleplay' in some areas lately, I found about it when Dr. Dino was visiting Deshima Station.  Since he's the time traveller character, he's often the one I go to other sims with the most (aside from an aborted attempt at RPing Grendel Footman's decendant in Insilico, first step in, and a GM yells at me about my skin not being realistic 0.o)
