There was a long spell where I mirrored my H. I would simply act like he did, with my limits of course. I wasn't able to be as cold as he was, at least I didn't think so. Then I flip flopped and I was just sweet as a danish roll no matter how crabby he was, and when I couldn't stand being so sweet any more I would escape his presence. Sometimes that wasn't so hard because he wasn't home all that much.

Then again if you're ok doing nothing then remember that is still an action.
