now this may be because we're on the way from one position to another, or it may be a traditional british approach, but i find this personally a great source of pressure because on the one hand i recognise as a parent myself one's going to have a crucial interest in the education of one's child, on the other hand how one reconciles those hundreds of different philosophies and then superimposes upon it a professional approach is, i suppose, the greatest single source of strain i find running a large secondary school, particularly, as i said before, in the end the responsibility in law is mine.
