One possible version

Good morning, ladies and gentlemen,

Some of us are having problems with our parents, as they often look into our schoolbags or read our diaries. I fully understand why we are not comfortable about it, but there’s no need to feel too sad. Our parents are checking our bags or diaries to make sure we’re not getting into any trouble. They have probably heard some horrible stories about other kids and thought we might do the same. Or perhaps they just want to connect with us hut are doing it all wrong. My suggestion is: Tell them we want them to trust us as much as we’d like to trust them. If you don’t think you can talk to them, write them a letter and leave it lying around—they are bound to read it.

Thank you !
