Bluntness ftw, I say it directly to people. Though I also talk and discuss things out loud with myself. Had to learn to tone that down when I joined, it "freaked" people out. I don't know why, I don't see why arguing differing aging theories with myself would be annoying to people nearby, I don't talk THAT loud.
The random high pitched cackling I can see being somewhat annoying though. But that's just fun, cackling I mean, not randomly annoying people. Though that does have its own appeal too... Dammit, this just seems to be a win-win situation, if the embarrassment of people looking at you like you're loony (which is a perfectly acceptable response, after I learned what people are taught by movies and lunatics) and then you get "counseled" by your OIC.
