I 1 my car, bundled my scarf around me and 2 up the street towards his shop front. The Street where his store was 3 was partially blocked by two large, ruddy faced workmen who were tearing up the concrete. I prepared myself for the 4 cat calls (起哄). I was up early, out in the cold, and probably to be seen as a funny scene by two men I didn't even 5 . Then I stopped and 6 my own father. Both he and my grandfather had 7 much of their early careers working outside in similar jobs before they 8 and became engineers.

One of them turned to me with a wide smile and 15 me with a joking "Oh lovey, you shouldn't have!" To his 16 , I passed him the tray with the two 17 chocolates. I replied," Maybe not. 18 it's too cold to be working outside today." I got two looks of genuine (真诚的) 19 , and a timely reminder that it's as easy to be 20 as it is to pre-judge-but the former is so much nicer! | |||
