Last week during our Physics test, it was super quiet through out D Hall(the hall that I have class in). There are only a few classes in it anyways(Its mostly science class rooms and the science rooms are twice the size of a History or Math class). I'm guessing most of the other classes had their doors closed. It was totally quiet in our class. All of a sudden in the hallway, we just hear this sexual moan.Everybody just looked up like "Whoa. What the heck was THAT?" and of course, people made jokes..
