You know you are obsessed with Death Note when...

when you correct anybody who gets the rules wrong... such as what happened to me
Random guy: isn't that show based on a notebook that kills people in 30...
Me: 40
Random Guy: 40 seconds?
Me: you also have to picture their face while writing their name. this prevents people sharing the same name from dying
Random Guy: oka-
Me: Also, if you specify the cause of death, write the details of death in 6 minutes and 40 seconds.
Random guy: well i...
Me: *listing many more rules*

 

LOL, Also, you know your obsessed when:

You have people call you by a letter...(my friends and I all call each other by the letter of our first name...)

When you have a printed picture of Rem, to use as a dartboard...(referring to Roxma's little L spoiler)

 

Ha one of my friends and I actually did the first one.

When you talk to the Shinigami following you around.

 

....you buy a cosplay Death Note, bring it to school, write the name of people who bully and wait for them to have heart attacks.

...you think talking to your invisible 'Shinigami' is natural.

...you go on the Internet and named yourself with the first letter such as 'J', 'M', 'A', 'Z' etc.

 

You hack into a police database and steal info about a certain case and to find prisoner's names.
