The sketchbook is Tyler's safe place. Which is ironic, considering its contents.
He draws and writes what he feels. This can be morbid, but it's the truth.
Josh reads it all.
Why?
He's not sure.
He know he shouldn't: It's Tyler's personal property, its none of Josh's business to know what goes on in Tyler's mind. But he couldn't help it.
Josh cried. Josh cried a lot.
