"No matter which one of you makes me a promise, I won't believe it, because the least credible thing in this world is someone else's pledge. For a promise made, it invariably becomes a lie as time goes by—all too soon, everyone fails to keep the promises they once made!
If you couldn't keep the promises you made in the first place, then why so easily make them to others? I remember everything you said before, no matter why you left me, but I will never forgive you again.
I know you are my dad and mom, and I'm aware that you are my birth parents. There are some things I can't change, but there are outcomes I can definitely deal with in any way I see fit.
I realize that you don't approve of some of the ways I handle things because they eventually hurt your feelings for each other. However, you have no clue why I became like this—why I made every decision I did. After all, there's always a reason behind each decision, isn't there?"
