I just thought up an awesome way to get her to drop that "friend" of hers, courier her a bag of doggy poop with the note "lunch?" inside it. Slip in the friends name onto that note too and get ready for fireworks the next day.
Dog poop never fails. Ever. Period.
Or.. or.... you could ask her to marry you. Chicks dig guys who love commitment. Go down on your knees in the class and ask her to marry you. She's already 16.. marriageable age. Should make a fine mother. You can name one of your kids after me if she actually agrees to. Or you can name your missing nut after me in case she knees you in the groin for being creepy.
Thank you.
