Sorry to hear of your bad experience at Langemark, Daniel, especially when you had obviously travelled so far to be there. Before I became a bookseller, I spent 6 years as a full-time battlefield guide, specialising in school tours. Like you, I have noticed that young people today do not grow up having learned the the things that we learned - such as being respectful in a cemetery, removing hats when eating, etc. However, I also learned that young people are actually very keen to do what other people might expect of them - provided that you tell them what other people expect. It's just that no-one ever has, I think. (Including whoever was in charge of their visit, I suppose.) Best wishes - Tom
