The Robot Devil is offended and screams, "Your lyrics lack subtlety! You can't just have your characters announce how they feel!" And then to provide an ironic counterpoint to his argument, the Robot Devil finishes up "That makes me feel angry!"

As such, you should be on the look out for how to convey emotions like grief or love to other players. Let's review some tips for that.
