You know you've read too much twilight when:
1) You talk about it so much that your brother went to the library, saw twilight on the shelf, was telling his friend that you are obsessed with the books, walks by this girl as he is saying "...and now she is writing the first book from a different perspective..." when the girl interupts him to ask if he is talking about twilight (after hearing only one line of the conversation) and then asks him out because she thinks it is so great to finally find a guy who knows about twilight.
2) You talk about twilight so much that despite the fact that he has never read the books, your brother is able to have an in depth conversation with the girl at the library about why Leah has not imprinted or been imprinted on.
3)You go to your bestfriends birthday party and meet one of her school friends, who gives your friend a copy of twilight. You kick yourself for not thinking of that only to realise that the girl who gave her the book is telling your friend about how amazing Jacob is. You practically rip the girls throat out and then don't speak to your friend for a week after she finishes Eclipse and tells you she is on team Jacob.
4)Your parents make you and your brother get out of the car and walk home because they are sick of hearing about twilight.
5)You make an agreement with your brother and all your friends not to talk about Breaking Dawn's plot in front of your parents because you fear they will take away your books if they find out the 18 year old main character had a baby. (We know its just not like that, that this is different, a one shot deal for Bella, but highly religious parents don't consider stuff like that)
6)You see this guy at school and mentally call him Edward because he looks just like what you pictured in your head. You pass out (almost) when you transfer into biology and discover the only open seat is the one next to "Edward". You cry for three hours that night because you found out his name is not Edward, but Danny.
7)You keep a copy of twilight in your locker just incase you need a twilight fix and the school library copy has been borowed.
BTW, all true stories.
