My wife and your girlfriend have a lot to talk about. That said, if she's grudgingly willing to suffer the slides the way my wife suffered a Jaguar hubcap I found on the street (Just lying there! Can you believe it?) being set up in our kitchen as the perfect wall decoration, then there's a future there.

Also I have a slide projector I inherited from my father, and now I'm wondering what treasures I might find on eBay...
