I am definately the Tolkien/LOTR freak in my house.
My dad (who doesn't count anymore since the mutiny

) might have read the books one time, and has seen the movies... but hasn't "gotten it"... like, when we're talking about it, he'll be like "the dead men of
what? "
My mom hasn't read any of the books, she saw the movies though... but doesn't take it seriously ('cept for Faramir.... she likes him...). Pretty much what she knows aside from casually watching the movies has been drilled into her brain by my incessant talking on the matter.
My older brother and one of my younger sisters have read the books, and seen the movies. They don't really get into it though. My sister does more so than my brother... fortunately (though when I start talking of the Elves, she starts walking away... I wonder why....) *looks innocent*
The others in my family have seen the movies, but that's about as far as it goes.
I haven't yet been able to convince anyone to read the Silmarillion... unfortunately. And as far as learning Elvish? Everyone thinks I'm crazy to even want to learn.
