How do I convince my parents to give me some freedom?

[Devika]

Please someone tell me, how do I convince my parents?
I am a teenager & I need freedom.
I just hate I when my mom & dad check my facebook account, check my WhatsApp, line, WeChat, twitter, read my dairy, check my cupboard, drawers, bag, purse, locker & spy on me whenever I surf the net, talk/chat with someone. When my friends call, or I call my friends, they ask me whatever we talked! They keep having doubts on me that I have a boyfriend or I watch p-o-r-n or do something bad! Well, the truth is, I'm not interested in any of those things! How do I tell them that I need some freedom, I can't share each of my own thoughts with them every-time, there are some things which I really can't share with them! I can't show them what I chat with my friends (girls only)! I also sometimes want to hide things, well, I'm not cheating at them, but I want my own space! I also wanna know, when I'm surfing & if my mom suddenly enters, how should I hide it?

Just talk like you become big .

And react like mature.

Just wake up soon in morning .

Avoid to play games and toys .

Avoid take money from your parents .

You want to know how to hide what you surf ? so do you have anything to hide ? You really need to respect your parents as they care about you.Stop all the resistance and wanting things your way.When you have kids of your own you will understand how your parents were just wanting the best for you and making sure you are safe etc.
Just have a word with them that you can be trusted and no need for all the snooping.Give them confidence that you can be trusted and im sure they will back off.

You need to tell your parents that your a matured big person and your not a kid and that your not some crazy nympho to chase boys or watch porn.

You've got to talk to them. Ask them if you are their step daughter and why they don't trust you. If they say that they are just worried about you, then tell them that you know how to take care of yourself and that you are not a kid and they need to give you your space!
Some parents choose to answer this argument saying "Do all this in your husband's house" as they probably think that your husband will take care of you. If that happens, then tell them that you have rights and that nobody gives a guarantee for future and that there is a possibility that you could get divorced or become a widow or your work or children require you be responsible for yourself. Basically, tell them that when they think they are taking care of you, they are really making you miserable and dependent on them, which will be bad for you in the long run.
Like that, argue with them and tell them that its not their place to spy on you.
Some parents might choose to still spy on their kid's phone and other things without their kid knowing. If that's the case with you, then well, when you chat with your friends, write in your chats about how you feel when your parents check your stuff. So, that way, your parents would understand that you not only feel your privacy going, but also you feel hurt about them not trusting you.
If you are really strong in the mind, then you can yell at them. But I think emotional blackmail works better. And don't think that you are doing anything bad. It really is not their place and they really have no business checking your stuff.
Also, set a password on your phone and facebook account and don't tell them the password. Tell them its personal and that you don't want to share it with them. If they are accessing your stuff from another device, then set strict privacy settings.
Also, if you think that they still have an access, then delete your chats. I understand that there are some chats that you want to preserve. But you can always save them some place else. Maybe, get a pendrive and save chats. You can also write your diary on a pendrive.
Set a new rule of 'knocking' in the house. Tell them its good manners to knock on the door before entering. If they come into your room unannounced, and there is something you want to hide, just plainly tell them that you don't want them to see and that its personal. Tell them that you don't sneak around invading their privacy and tell them to treat you with that kind of respect.
Please understand that you don't get anything unless you ask for it.
Above all, don't give them all details about everything in your life. This probably happens with you because you tell them everything and so they are under the impression that you don't mind them sneaking into your stuff. So, when they ask you say "How was the party?". Just answer with "It was fun" or "It was really good". Don't get into details about who wore what. Maybe some details. But not too much details.
Anyway, I must warn you. This might turn into a fight. So be prepared. And understand that, you have rights in your own house and that nobody can deprive you of them. Not even your parents.
Best of luck and tell me what happens.
I have kinda been through this kind of thing. Like, my parents don't check everything out, but they do kinda ask a lot of questions. So, basically, I think I might be able to help you further if this goes bad.
Hope I helped.
