pop quiz

Was in a class or something and the instructor told us to be ready for a pop quiz. He wanted us to state which of the things we have discussed are theory and which are law. I thought it was easy and went to a vending machine on break to buy some crackers. THen I couldn't figure out which # to push in and someone came behind me and pushed what they wanted and took it. THen I tried again and got my crackers. Everyone else in class was stressing over the quiz and were studying. I wanted to explain to them that it was simple etc., but then I figured they would just stress more. THis one gal was reading in her books. She had two books for the class when I only had the one. I said. well I'm sure you will do good etc..
