About 15 years ago I went on a few dates with a girl who was into the EU. It was interesting ... and weird. Reminds me of the Seinfeld quote: "All of a sudden it hit me, I realized what the problem is; I can't be with someone like me. I hate myself!"
My wife tolerates my Star Wars fanatacism. She doesn't sit down with me and watch the movies, but my 2 sons do. That's good enough for me. She's even asked me if I had any interest in joining the 501st or Rebel Legions.
However, she shot down my idea to display, in our entertainment unit above the TV, all 12 vintage action figues in the original display stand. Of all the nerdy things I could do, I though that was pretty classy.
That said, if she ever tries to put an Edward Cullen picture anywhere in the living room, I swear there's gonna be a fight.
