" There's a thing that happens in Hollywood, when you hand in a script with magic in it, and the people at the studio who read it say " We don't quite understand... can you explain the rules? What are the rules here? The magic must have rules" and sometimes when they say that to me I explain that I am sure it does, just as life has rules, but they didn't give me a rule book to life when I was born, and I've been trying to figure it out as I go along, and I am sure it is the same thing for magic; and sometimes I explain that, yes, the magic has rules, and if they read again carefully they can figure out what they are; and sometimes I sigh and put in a line here and a line there that spells things out, says, YES THESE ARE THE RULES YOU DON'T ACTUALLY HAVE TO PAY ATTENTION and then everyone is very happy.
