Well, now you're just being irritating.

The whole point of being in the ISS (and even the Order, for that matter) is not having to act like anything.

I don't want you to act like you're not upset, you prat. I want you to not be upset. Which means figuring out what exactly's upsetting you.

I know everyone's new. You've got to give them a chance and get to know them, and then you'll be all right at doing normal things.

Or if you want to look at it your way, I suppose you should pretend to be having fun and sooner or later, you'll be having fun.
