But it will be filtered through his own comprehension. Then we all get to play: "What the fuck is fatty actually talking about?"
The thing with Chris though is that whenever he brings up something bad that happened to him, you can safely assume that's true, since he's loathe to bring that sort of stuff up about himself.
For instance, Chris's graduation. We all thought, from the way he described it, he was upset and just stomped across the stage, grabbed his diploma and ran off the cry, making his parents upset. Just in the last few years, when he reminisced about it again, he let slip the fact that when his principal went to shake his hand, Chris slapped it away. He has no reason to make that up, or misremember, because it's a puzzle piece that fits in with the official story, about how Bob was really disappointed in him.
The Nathanael Greene tard-correction gets another little tidbit of information from Chris in these letters as he vents, that a teacher put him in a choke hold and how this recent event was much like that. This gives huge amounts of credence to the theory that Chris went violently insane, needing multiple teachers to hold him down and one to put him in a choke hold most likely to prevent him from attacking someone. If Chris was just uncooperative or even just yelling and screaming, I highly doubt it would have blown up into the big thing it did and I highly doubt Chris would just invent something like that since it doesn't make him look good.
...or even his classic Target freakout, where it took multiple police officers to pin him down, hogtie him and carry him out of the store. Chris has a very distinct history of flipping the fuck out, and while a habitual liar, he's not a very good liar, so time removed from these events means Chris will lose the narrative that makes himself look good, and will yammer on, occasionally admitting to getting into that situation due to his own, really asshole decisions.
