Perfect thread for me!
So, I'm aware of the different terms for CTB. Cease to breathe, catch the bus, etc. But I was unaware of the term "close the book" until I saw someone on here say it, and I immediately was intrigued.
Catch the bus seems to be the most common iteration, but for me, it doesn't fit. Buses go somewhere. Buses travel. Even when you "take the bus out of town," it will travel.. somewhere.
I don't want to think about where I'd go after death, at least not now, and especially not in my darkest moments. For me, CTB (if I'd ever do it) would be an end, not a new beginning. I want the pain to end, simple as that, close the book, done.
Oh, and when I was younger I liked the movie Book Of Life. That was an afterthought.
