In several things, the US doesn't behave the same as in Europe, you would think they would more but they dont. The system described by the poster does sound interesting. I dont see where it would cause any harm, but it is definately different from anything we have here. When I lived in Spain as a child, I went to a British private day school. It was very small, maybe, 200 students total. It was 1st through 5th grade. Several Americans attended, as well as Australians, Brits, and some half Spanish half British children. But to me, coming from the US, our hours were odd. We didnt start until 9 am, and didnt get out until 4pm. We had a long midday lunch/playtime about an hour and a half. Spanish businesses mostly opened around the same time, 9 or 9:30 (stores and offices both), but all closed for lunch, for either an hour and a half or 2 hours. Then offices would stay open until 6 or 7 pm. Stores stayed open later, til about 10pm. People ate dinner between 8 and 10pm. It all seemed odd to me but perfectly normal to them. With the midday rest (siesta) it really didnt seem weird staying up so long once you got used to it. I think its all in what your culture is used to. What seems normal to us probably seems odd to Europeans also.
