"Can I explain why I wanted to jump off the top of a tower block? Of course I can explain why I wanted to jump off the top of a tower block. I'm not a bloody idiot."(From A Long Way Down by Nick Hornby)
Nick Hornby's A Long Way Down was recommended to me by a relative as a surprisingly funny book about suicide. This opening does set a witty, sarcastic tone, and if you're going to read a book about suicide, it helps if it's witty and sarcastic, right?
