This thread cracks me up every time...
When you brag about knowing the names of all the actors and actresses who play the main characters in the movies, from Haldir (Craig Parker) to Denethor (John Noble).
^It annoys people, too.
When any story you write ends up having a character in it who is oddly similar to one of the characters in LOTR, and people notice ("Isn't this guy a lot like Aragorn?" "Um.....no.")
If the characters aren't similar, then it has fanfiction-like qualities (you know what I mean)
When you couldn't find your hardcover copy of LOTR and declared it a "state emergency" and demanded your entire family help you search.
Not that I've done any of those things.........
