Nothing happened. No matter how long you thought you wanted to believe, the book didn't budge. Any other object didn't budge. You grew tired. This wasn't like studying. There the mind kept itself occupied. Now you were just continuously telling yourself you wanted to believe. No matter how hard you tried. No matter how much coffee you poored yourself, eventually you noticed your head was resting on your arms on the table. 

The clock noted 8 am, which meant the store should open soon. But just as you realised that with a start, your hand hit against the mug, spilling fluid all over the book. Damn it! 

Wait a minute... Didn't you distinctly remeber setting that mug down further away from the book so as to prevent this? Or had you been too tired to notice where you put it down last time?
