<human>: Can you provide a brief rundown of the text in within 3 sentences?

My dad remarried and his new wife had 3 step-children who lived with us. I never really interacted with them, but they always had a grudge against me, especially the mom (ugh, that's another story). I guess this is a full circle revenge story.

I find out my 14 year old step-sister is telling guys from Myspace to secretly sleep over. I was like, oh hell no. As dramatic as it sounds, if she got knocked up, I did not want to hear a baby crying in this house. I informed my dad and she got in trouble. She (or my step-mother) get revenge on me by hacking my Myspace account which I kept my private diary on. I had recently posted about an old flame, even stupidly including his name. I get a message on Facebook from that old flame saying I almost ruined his current relationship because of my "shenanigans" and to leave him alone. It was a RE: email, so I must have sent an email to him first. The title said: "RE: I have a problem". I wasn't able to see the email "I" had sent even after begging him. Who knows who else they contacted.

After awhile, I get this genius idea. I get the cat poop from the litter box, slice it open so the feces is fresh and rub it on the inside of her pillow case. I made sure to not make any marks, just a strong poop smell. I smeared it on other things like her door handles, etc. I have no idea if she noticed or blamed me. Ever since then, she cowers and gets scared if I cross paths with her outside.
<bot>: I tell on step-sister for trying to sneak boys over. She gets revenge by hacking my Facebook. I end up smearing poop on her pillow case.
