The Truth About "Truth"

For Wolves in the Walls, the truth is only known by an innocent child. When trying to explain, she's ignored, her point being viewed as a ridiculous idea from a mere child.
In “How to Tell a True War Story,” the truth is only known to the soldier. If the soldier went and told a war story, the listener would end up being concerned only to its validity- which, to the soldier, did not matter; the story is real whether or not it happened.
Dickinson’s three poems describe Truth in itself. The first, about how it must be told: in moderation. The second, how it is unfailingly strong. The third, how timeless and enduring it is.

The three (I missed one of the children's books) have their own spin on Truth, but compare in the way that they view it is up to the interpreting to know Truth itself. They also recognize the power of Truth- how it may be voiced as a warning from a child, a memory from a weakened soldier, or exist in a stronger form on Earth than what is tangible-, and how it takes a patient listener to recognize Truth.

I liked O'Brien's "How to Tell a True War Story," most, maybe because I know the rest of the book as well. While reading it in my English class, some of my classmates were very hung up on what was real or not. However through discussion and prompting from the teacher, we arrived at the conclusion that why should it matter?
What's written is written, what's read is read; what O'Brien writes are memories from his head.
Whether or not the stories actually occurred is irrelevant. They could have happened, and that is the only truth needed for something to exist- the mere existence of possibility and someone believing it is true.
