To Miss/Mister Nobody:
I am so pissed off by you. And I seriously thought you were one of my 'good' friends when the truth is you're biting me behind my back. I thought you are one of the people whom I can rely on, but sadly, you are far from it.
I have tried to be nice to you and all, and you wasted the trust I gave to you.
Gah, I am so disappointed with you.
