oh, and then there's the meta level:

sometimes if SP needs to be told about something he's doing that's irrational, SSP will tell him about it.

sometimes if CP has something that he's having trouble introspecting on, CCP will help him introspect on it.

sometimes if PP needs to be warned about something he's doing that's dangerous, PPP will warn him about it.

sometimes if HP feels left out because he doesn't get to have a meta-level, HHP will say something just for fun :)

oh, and I tend to not pay much attention to what pronouns I use. I use he, she, it, and they kinda interchangably. I also don't pay much attention to whether I use "I" or "we". I often end up accidentally using both in the same sentence. You're welcome to use whatever pronoun you find most convenient, when refering to any of us.
