How many days has i been?
I like what you are doing there, CF and doing the 'push-pull' thing
I think you just did overkill slightly in that it was about 3 neg's in a row
So this might have been better to lean it out a bit:
"Don't tell me you're one of those crazy True Blood fan? The girl I used to date was one of those. do you stack that True Blood synthetic blood bottles in your fridge like she did

? ...... lucky you're cute because that would be wayyyy to weird for me

'
So there was like a neg in there and then also a small complement to balance it out a little, and also you have left a hook in there where she may feel obliged to come back nd defend herself....i.e. to say that she doesnt do that stuff and to try and make it ok that she likes true blood
I think lots of younger kids like it as well so heres another idea just to show you:
"Don't tell me you're one of those crazy True Blood fan?........I thought it was just under 16 or year (whatever the school year you want to use) who like it & buy all the books and stuff...... lucky you're cute because that would be wayyyy to weird for me
