Outgrowing the truth is a perfect symbol.
That's exactly how I felt.
It felt so pretend and fake. All of it! The people, the fairy stories, the idea that we have a big secret that the rest of the world just doesn't get. It literally became laughable to me toward the end. It still is to some extent. Sort of like a grown up remembering when they believed there were boogey men in the closet.
Once I hit my teens the Troof never really made sense to me. I struggled with that feeling of not belonging. Like I was the only one who didn't get it. Finally I woke up and realized how futile it was to waste anymore time on their nonsense.
