Talking in your sleep

As a teenager, I used to talk in my sleep, according to my mother. Sometimes, she knew things about me she wasn't supposed to know. I always tried to figure out how she found out! She always said: you talk in your sleep!

Coming back from the US, where I worked as an au pair, I cleaned up my room so it could be more of an adult room than a messy teenager bedroom. Under my bed, I found my little metal locker, that my mother gave me after my brother distributed copies of my diary to all of his friends. At the time, I was devastated when I found out and ran home, all teared up. My mother said that was not done! and she bought me a metal locker and a brand new diary. I felt safe again. I gathered all my private belongings and kept them in the locker. 

It was not until I came back from the States, that I finally found out how my mother knew all about me. I was looking for my school diplomas in her bedroom and I came across an envelope in her drawer. It contained a key.. it looked pretty familiar to me. It was the spare key of my "private" locker.. 

So don't tell me I talk in my sleep.
