As a teacher I spend a large proportion of my time asking people to be silent, or at least quieter. I accept this as part of my job. Crowds of people, of friends- not just teenagers, like to communicate and this creates noise. Of course, the energy and excitement and impatience of young people can be headache inducing. This I accept. But I am concerned that their constant need to talk or listen to music means they are losing touch with silence: the opportunity to think, to occupy themselves without constant aural stimulation, to just be. They need to learn that silence can be cherished as well as feared. We all do!
