How should I get revenge on my step sister?

Question

heres the background:

each weekend my sis goes to c her grandmother, mainly because theres a dog there.. her grandmother is really evil to her, and she comes back and she takes out all her anger out on me and my mum, we never do anything to her, the things she does can range from those little lies that get you shouted at when you've done nothing wrong and telling the World that you tried to strangle her when there are witnesses in the room that say otherwise, seriously she's making my life a misery and all my Mum and step dad do is shout at her for a min when she does something wrong which of course doesnt stop her. so its just a continuous circle and me being destroyed weekly.

I've tried everything: being nice, ignoring, u name it, so don't bother telling me how revenge is not the answer cos it really is. It makes me feel better. and if you've read this far you know she deserves it. telling me revenge is not the answer wil not get you 10 points

Answer 1

every times she goes to her grans take something of hers that means the world to her ... if she is mean cut it up infront of her but be4 hand say if u stop doin this i wont do thids (cut cut cut ) after a couple of weeks she will see tht if she wants her beloved belongings she needs to change her attitude.. it will work believe me oh and if she tells mum or step dads say she did it in angry rage tryin to frame u

Answer 2

k den i think that first dis is kinda like a prank i think that u should pick some worms off da ground n put dem in a bucket n wen she is not home u should put da worms under her pillow n attach a note like u mess with me, then i mess u up or something so wen she is sleepin they crawl out.   i will think of better revenge srry my brains not proper now, brb.
