Reasons why I should have more privacy online?

[its.Kaylaa]

Today I had an argument with my mother about how I need more privacy. She doesn't understand that privacy is all teenagers my age want online (I am 16 years old). I ended up deactivating my facebook and twitter, only because I'd found out that my mom got a notification for every status update, and looked at my page on twitter whenever she found out I tweeted something. I mean, I know that there are creeps out there, but I'm not stupid. I don't add people or let people follow me I don't know in anyway. That's her only reason she has, and my only reason that I can think of is that I need privacy. She doesn't even knock before she comes into my room or bathroom.
Also, everytime I blocked her from a status update, she got around it somehow.

Do you have any better ways to say what I need do say, or some sort of compromise we can come to?
