Before you picked to read thing you where in a state of Quantum superposition of reading it or not. Imgaimng when you make a choice you are on a bringe and there are a infinent number of you, you go one way half of them fallow you and then the other half go the other way whem you are on the side the bringe breacks and there is no going back.
