I want to kill blondie - part I

Ever had that one person that just digs at your skin more then anyone else?? That stupid dumb bitch that can't handle her drinks or drugs. The one that thinks its ok too talk about every guy she has hooked up with right in front of her boyfriend.. or talk about sexual encounters with the one that has stolen your heart. Well it was about time blondie learned her lesson. After 8 years of this girl being in our group i decided it has to stop and i am now plotting against setting out too hurt her. But i can't do this in any obvious ways, shapes or forms as i am still close to her family and would like to remain that way.
