How can I get my stepsister back?

Question

My step sister is 10 almost turning 11 and she is so immiture.
I only live with her on the weekends and I can barely take it!
She steals my stuff and gets away with it because she never leaves any evidence and I already asked my dad to but security cameras in my room.He said no.I can't put a lock on my door because my step mom has to put her clothes in my closet.
My step sister never believed in anything like santa or the easter bunny and that probally ruined her spirits.Also, I am 12 so we are kind of close in age like 1 in a half years so my family says we should get along great.She acts like a immiture,mean,rude, 8 year old.I am always nice to her even though she yells at me.She treats me like I am younger than her.And the worst part is, she thinks I like her and she yells and screams at my step mom and my dad.My dad wants to tell her to stop and punnish her but my step mom won't let him.So, she gets to keep yelling.I could go on forever but I can't so,How can I get her back

Answer 1

The fact that you are giving her attention for her bad behavior is most likely making things worse.

The best way to "get her back" is by training her like an animal. Many animal training methods work on people. If you follow the methods you will be able to modify the behavior and will have the secret knowledge that you have treated her like an animal.

One method "lease reinforcing behavior" might work on her. You stop giving her attention for bad behavior. Right now you are giving her attention when she does something bad...she most likely enjoys the attention, therefore you are only encouraging her to perform more bad acts.

Instead you should give her only positive attention and that positive attention should only be given when she acts in ways that you like. Even if the improvement is only minor you should give her positive attention.

There is a link below with more information on animal training. You can find a lot more info on the web.

Answer 2

Your step-sister does like you and is doing all of this stuff because you don't seem to like her or want to have anything to do with her. If you treat her nicely, then she should stop after a bit. I know that's hard to want to do, but your only other choice is to do the exact opposite, which would be to ambush her somewhere and sometime when nobody is around and tell her that if she doesn't stop it you'll beat the crap out of her and blame it on a schoolmate.

Answer 3

the great prankster that previously answered missed a couple of real gems.
short sheet her bed
wait until she's asleep and put her hand into a large bowl of warm water (she'll wet the bed)
tie all of her shoe laces together
put itching powder in her underwear

most importantly, be creative and fun. You want to pull silly pranks that you can both laugh about later.

Answer 4

if your step mom doesn't punish her she wont punish you ask for a safe or even better your almost the same age so stoop to her level here are some pranks
hot coco powder in the shower head
pennies in her sheets
fake bugs/snakes in bed
switch all of her clothes around in the drawers
put ketchup or mustard packet fold it in half and put it under the toilet seat
tape shampoo bottles shut
tobasco sause and other iky things in food and drinks!(that 1 is fun)
steal her stuff and start ignoring her!!!
me and my brother are like you and your sister and after the toilet seat one he stopped!!
tell your parents how you feel about her and after doing the hamless pranks and theyask you why tell them again.

Answer 5

Well, just sit her down and talk to her, but if that doesn't work you should play some harmless tricks on her, girl!1and if your stepmom and stepdad asks you why you did it, sit them down and justtell them everything that's on your mind,you say you can't take it anymore, so you can either do it the easy way or the hard way!!!gotta go, bye!

Answer 6

First you treat her as your own sister, but not as your step sister. you are elder to her and it's you to bring her on to right track. if she goes on yelling you, then you go on loving her. one day she will definitely understands your love, and she will be back to you. because love can change her and make her to understand you.

Answer 7

just isolate yourself whenever she's over...completely ignore her, kids hate the silent treatment, do it for like 2 months

Answer 8

go buy hair removal cream and put it in her shampoo

Answer 9
