According to the Constitution... "I love you"

I was in grade eight. One day something happened to my locker and I was unable to close it properly. I was kinda in a hurry so I decided to leave it the way it is and ran to my classes. I remember taking Law that term and it was one of my favourite classes. Yeah I wanted to be a lawyer back then. So one day I opened the Constitution in class and found this lines: "I love you cutie". I was like: "Who the hell could write this and how did he/she get into my locker?" I told my best friend about it and she was surprised too. So out of curiosity I decided to leave the locker unlocked. Every week this mysterious guy left me messages on the first page of the Constitution. Once he even put a postcard in it. I tried to find out who is it, but I never succeeded. I even thought my friends were making fun of me. But noone was aware about this story. The last message I received from him was "I miss you" and a little present - a snowball with a cute monkey holding roses. I am still keeping it in my room.
