My major role play annoyance is when people just ditch you after you make the first post. I HATE IT! It's like we put all this effort into planning and talking that I like you enough as a partner, we then sit down and start the sucker and what do I get. They leave. For the love of God, have the metaphoric (or literal) balls to tell me you don't wanna RP anymore.

The other thing that makes me mad is characters that aren't believable. Sure I don't care if it's a little off, but don't make it painfully off if we are RPing something historical. My favorite story is someone I once RPed with tried to have a Greek goddess read a Mark Twain book. Then I also had someone make a Chinese charcter who didn't have a Chinese name nor have any Chinese features (this RP was like Marco Polo traveling to the East and she was a charcter from the East). Simple accuracy matters to me. It's all I ask.
