How to avoid an older sister that has mood swings constantly?

Question

My sister is really annoying. She thinks she has the worst life in the world, when she actually has life good. She despises my family, run away over a long time, wants to move out, and is a freeloader who does nothing but waste energy and time. She has a boyfriend to where she wants him to beat me up. I am 3 yrs. younger than her(14) while shes (17) trying to be 22...
in my opinion, shes almost 6 yrs. old
Also, she never cleans her room, never cleans the house, etc.
For example, I accidentaly leave a mess in the kitchen, and she says" Y r u leaving this mess for me to clean up!?" and i start laughing cuz she doesnt clean. Plz help me out with this annoying problem.

Answer 1

umm well
tell her to stop being like this that she has no right to talk and treat you like the way she is
donm take her crap lol give it back to her
tell her that she dosent do anything either i mean sometimes bringing it up to them annoys them and then they willknow how you feel....so i mean dont sit there and stay quiet about it be annoying right back...lol :)

Answer 2

A thing to look forward to is that she'll be 18 soon and then she can move out. Until then, all I can suggest is to stay out of her way. When she is home hang close to your parents (a suckey idea but it works), stay in your room until she leaves. The next time she comments to you tell her that you have problems of your own and that you wish for her to leave you alone (if she has any feelings towards you this may get her to think she's not the only one unhappy). My sister was like this and even thou I tried to be as nice as I could to her she was still a pain. As for her stupid boyfriend, if he touches you, call the cops & have him arrested.

Answer 3

You seem very calm and nice :) Well tell her she needs to fix these "annoying things she does" becuz when she grows up, no one is going to like ehr becuz of her attitude
