quicko: hens and weddings

American girls have bachelorette parties before their weddings; Australian girls have hen's nights/days.  I've recently been invited to a hen's celebration and have been researching protocol to be sure I get it right.  It's a good thing, too, because it turns out they're slightly different.  This Australian party is an afternoon of fun scavenger hunting in the Rocks.  It has an admissions fee, though, I've thankfully just learned, no present/card requirement.  Thankfully because I could really have embarrassed myself, seeing as bachelorette parties are generally the time to bring the sauciest underwear imaginable for the bride-to-be.  (This can also be done at the American bridal shower -- and there are generally two; one for the friends to bring underwear and one for the relatives to bring practical things.  (The difference between the saucy bridal shower and the bachelorette party is that the shower has a wider guest list, is an afternoon sort of event well before the wedding and often includes silly games, etc.  The bachelorette party is more of a pajama party for a select number of close friends -- more of a night on the town affair just before the wedding.)  The Australian bridal shower equivalent is the kitchen tea, which is only like the latter type of American bridal shower.  I'm not exactly sure how Australian girls get their ... trousseaux, if you will ... but evidently it's not my job to provide too much of it for a friend.  I think ...)
