So it goes

Billy Pilgrim finally leaves us at the end of the book and we are brought back to the first person we met in this book, Kurt Vonnegut. He tells us about what Billy does after Dresden. He explains some reasons for the story and he tells us about several people who have died in that year. So it goes.
This makes me think of today. During that time Robert Kennedy died, Martin Luther King died and his father died. He starts the chapter with so it goes. He talks about the soldiers of war and that brings me to today. Now there are soldiers of war in the middle eastern world from the USA that have died and this year many famous people have died. So it goes.
