My mum used to go through my things. She'd deny it of course. I still wonder what on earth she used to find so intetesting in a boring (generally good) teens bedroom.
She used to read my diary. I caught her once. She denied it even stood there with it in her hands. My Dad said she was just picking it up off the floor (I'd hidden it, she hadn't just found it). After that I kept writing in it but knowing she'd read it, I wrote boring stuff but also peppered with how much I hated her. I sort of feel bad now but equally I dont. If she had given me some privacy, I wouldnt have done it.
My son and I stayed the night recently. She went through our bags when when we out. My son accused me when his stuff had all been moved! I didnt see the point in making a fuss over it so I said that nana must have moved the bag to get to something in the room and accidently tipped it out. He believed me. What she expected to find I dont know.
I moved 200miles away for uni, never moved back and now live almost 300miles away. A huge part of moving away was privacy. She moans now that she doesnt see us.
