A person who's reading twillight brings it up in a chatroom.
Me: Vampires don't sparkle, 'nuff said.
Twillight person: Hmm? Oh, it's just a new way of thinking of vampires.
Me: Vampires. Don't. Sparkle.
Twillight person: They do in this story... - -'
Me: Vampires. Don't. SPARKLE! D8<
Twillight person: Take it easy, dude! O8<
Me: ASDF-BLARGH!!!
*Moment of silence*
Friend: Trust me, stop talking to him. He bites if you go to far.
