Dear Anonymous,
See? It's appearing. You can't hide it anymore. When we first met, five years ago, you were such a perfect faker and an amazing friend I couldn't believe it myself; but only two years ago, when we got to know each other better, did I know the truth. I used to hate that poor girl, but now I really sympathize with her, one of the reasons being the way you treated her. And don't tell me she lied; it was her parent contacting us, informing us that it threatened her. Afterwards, I was asked by several people the same question about you: "What HAS she done?"
What HAVE you done? ...Honestly, I'd rather not mention the things you've done. In case your worrying about what I said to those people, I just smoothly changed the subject.
I'll never forget that ugly smirk you'd have on your face when you did the things you've done. How could I have fallen for the trick? I struggled against my emotions. I didn't know what to do. Was it just a mistake, a once-in-a-lifetime mistake? That's what I decided later on two years ago.
Thankfully, though, that girl appeared the next year and showed me the truth. Not that she was better than you are.
How could you invent such lies about an innocent person? So maybe she had her own faults, but we had nothing to do with them! Couldn't you just have left her alone?
She showed you something I wrote she wasn't supposed to show you. Though now that I think about it, I never really told her not to. Anyway, that just confirmed your two-faced-ness.
I don't know why I'm doing this in the first place but I am.
-me.
