I am sick of my parents trying to blackmail me. How can i hide a facebook account from them?

[Katarina]

Im 16 and basically ive been asking my parents for facebook for years. At first the reason they said no was because they were teachers. Then, because they dont know anything about it. Then because they dont like it. Ive explained everything to them and my nine yr old sister has kik, but they wont let me have facebook. The problem is that EVERY SINGLE PERSON around me has facebook and the fact that i dont makes me socially withdrawn and i cant contact friends that go to other schools. Now they are just using it as an excuse to get me to do everything for them. They want me to tidy up the whole house, cook dinners, do every single chore they can thing of .... And then maybe they will THINK about it. Im just sick of it, its not even about the facebook anymore. I just really want to be able to chat with my friends but my parents are so mean. They dont even want the best for me or anything, ive explained everything and they understand. Dont try to talk me out of it, because i am definitely going to make a facebook account, right now. The problem is that obe of the friends i would have, her mother is really good friends with mine and she checks her daughters account. So she would see me and blab to my mother. Also, im going to put it in my own name so i dont think she will know to do this but she could search my name and see that i hav a profile. Oh, this is really tricky, but i hav just had enough. Pls, pls help me. Dont try and talk me out it, cause i wont be persuaded. Just please try and help me figure put how i could keep it from my parents. The making time thing wont be a problem, but i just want to make sure that she doesnt find out. Sorry this is so long and thankyou.
