How much privacy do you give your preteen? At this stage DD11 has privacy in the bathroom, i.e. you must knock and she will decide if she wants to let you in, but she still regularly invites you in for whatever reason and also walks around the house naked.
Room - she doesn't want us to go into her room without permission, whether she is there or not. I think this is a step too far, it is still a part of our home and at this age we need to know what she is getting up to.
Electronics - we reserve the right to look at what she is doing on her laptop at any time, as well as access email. Her cellphone went through the wash (and died) and she doesn't feel like saving up / working for a new one so that's not going to be a problem any time soon.
