eleven o'clock at night
In Germany you must not leave your front door unlocked after ten o'clock at night , and you must not play the piano in your own house after eleven . In England I have never felt I wanted to play the piano myself , or to hear anyone else play it , after eleven o'clock at night ; but that is a very different thing to being told that you must not play it . Here , in Germany , I never feel that I really care for the piano until eleven o'clock , then I could sit and listen to the `` Maiden 's Prayer , '' or the Overture to `` Zampa , '' with pleasure . To the law-loving German , on the other hand , music after eleven o'clock at night ceases to be music ; it becomes sin , and as such gives him no satisfaction . The only individual throughout Germany who ever dreams of taking liberties with the law is the German student , and he only to a certain well-defined point . By custom , certain privileges are permitted to him , but even these are strictly limited and clearly understood . For instance , the German student may get drunk and fall asleep in the gutter with no other penalty than that of having the next morning to tip the policeman who has found him and brought him home .
