You prove you are truly obsessed with LotR when:
someone asks you what your Evenstar Pendant is, and then they add "Oh, must be something from that Ring movie."
While playing a game in science class, my teacher (who is a fan of the movies) asked about 10 LotR questions. I ran to the marker board and answered all of the questions correctly, allowing the girls team to win. The boys don`t let him ask LotR questions anymore.
I`d like to add that yesterday, I went to the orthodontist and chose dark blue and silver rubber bands because they reminded me of Gondor.
