Greet and shake the hand of the ladies before the men
But wait until a lady offers her hand first (if you are a man).
Continue to take them off even if they say there's no need when you've got them half off.
Yes. They always say, "Oh, don't bother," but it's just part of the ritual. Take them off, whatever they say.
never, ever, shake hands across the threshold
A student of mine recently denied being at all superstitious, but when I suggested he shake hands across the threshold he said, "OK, you got me there".
This superstition runs deep and should be remembered.
If they open a bottle, pace yourself. There's no disgrace in drinking only half a shot when the more macho guests knock back the whole glass. Stay sober. The women will not look kindly on a guest who has to be poured into bed.
