OH GOD WHAT TO DO NOW? How can he know my secrets..is he hacker or something!! I cant make him stay in my room! He is so irritating!!! Funny thing now he is my MATHS TEACHER also..SOMEONE SAVE ME FROM HIM!!" I wrote it in my diary. my 15th birthday and a bomb drop on my head and everything changed.
