Life is a very orderly thing but in fiction there is a huge liberation and freedom. I can do what I like. There's nothing that says I can't write a page of full stops. There is no 'should' involved although you wouldn't know that from literary reviews and critics.
I doing casual labor by the day. They wouldn't pay you until the next morning. There was a bar that would cash your check if you bought a beer first. A lot of guys never left until they'd drunk up all their money.
