| When I was in Germany, one day at Christmas-time I went to a post office to send a letter. To my 1 I found people queuing (排队) some paces away from the person at the saving deposit window. 2 so? Each did his business 3 but the line never moved a step 4 . I was very 5 , so I walked to the window to find out the cause. There was a notice on which was written "Thank you for your 6 for other's privacy (隐私)" -a polite 7 to keep people away from interfering into other's 8 (money matters are regarded as privacy in Western countries). I was deeply impressed by the 9 and stayed a while to watch: they were waiting so 10 at a distance that they seemed quite 11 to the practice. The 12 thing happened at a public telephone box. 13 waiting for their turns always kept their distance-enough to be out of 14 . It's another typical example! From then on I 15 to watch their ways of doing things, manners, treatment 16 towards others. I found the Germans always mindful of other's privacy. They avoided putting others in an embarrassing (窘迫) situation. For instance, they never 17 about age, incomes or the place to buy such a coat, 18 would they comment on the others or jewelry others wore. Their laws 19 reading diaries or opening letters without permission. That shows 20 matters are not allowed to be disturbed. | ||||
