Paraphrase of a dialogue we had some months ago:
Mast: I know the only thing I have to do is show up here, and talk.
T: As a matter of fact, the only requirement is that you show up.

So that seems to be the only expectation he has. However, since we have worked together for two and a half years, twice a week, I think he probably expects things from me based on what he knows about me. I know that he assumes that I'm being honest, or as honest as I am capable of being; I might misremember things, but I won't knowingly lie to him, and I might leave things out of my stories, but I'll always tell him when I do that.
