My mother and my little sister are constantly arguing. Usually my mother is angry at my sister for not doing something that she should have, then my sister speaks back, rinse and repeat. Even though I'm not involved, it's incredibly annoying. The house is never quiet. No, I can't move out.

How do I find some peace and quiet?

Easy.

Visit your local library.

(and PBSkids.org)

book them a family counseling cession?

Talk to them about it, tell them that you don't feel you have a place to be at home because they're always fighting.
Be sure not to tell them while raising your voice, as it could evolve into a fight aswell.
Best of luck (:

(4 here, new computer xD)
Well.. My famly had a problem with arguing, it was like a battleground whenever you came home. I one day i was really fed up with it so i asked them if we could sit down and talk quietly about it, about what we could do to emprove things around the house and the whole atmosphere, what was bugging us and what we could do to make the day less stressful. It really helped, and i love being at home now ^^.
I know it might not work in all familys, but it's certainly worth a shot ^^ ..

>>7 6 here. My people are so stubborn :( its very complicated. That's why i want to go away, as far as possible for quite a while, to heal from all this stress and stuff! I don't even want to talk to them anymore. Yes, i'm avoiding. But im not op, i guess OP could try your trick! :)
