I was sitting in my ethnomusicology class today watching a video about Japanese court music when I suddenly and quite unexpectedly heard the unmistakable sound of an approaching didgeridoo. All heads turned and looked out of the window in time to see my dear friend Bob bark at something from the second story balcony of the music building. He was with two other guys and one of them had the didgeridoo. They laughed and moved on, leaving my classmates stunned and confused. Luckily no one saw or heard me snickering in my seat at the back of the classroom.
