I definitely wasn't cool in high school. I really wasn't. I did belong to many of the clubs and was in leadership on yearbook and did the musical theater route, so I had friends in all areas. But I certainly did not know what to wear, did not know how to do my hair, all those things.
I lived on the top of one hill and the school was at the top of another hill. Nobody ever went to school by car - we didn't have any cars during the war. So that to and from school was itself a training.
The director's job should give you a sense of music without drawing attention to itself.
