Well the youngest member of the group is going as Bonnie with her boyfriend as Clyde, so that's where the idea started, and it's a party theme we were going to use for a midsummer party that we never got around to throwing.
I never usually bother with spooky, since this place manages to do that all on its own, spooky and also mildly disgusting all the way through bloody terrifying and a godawful mess to deal with.
But I think I could make an exception, especially if my mom lets us use the guildhall.
