I used to live selfishly, I should admit．But one moment changed me．
I was on my lunch break and had 1 the office to get something to eat．On the way, I 2 a busker（街头艺人），with a hat in front of him．I had some 3 in my pocket, but I would not give them to him, thinking to myself he would 4 use the money to feed his addiction to drugs or alcohol． He 5 like that type-young and ragged． 6 what was I going to spend the money on ? Only to feed my addiction to Coca-Cola or chocolate! I then 7 I had no right to place myself above 8 just because he was busking．
I 9 and dropped all the coins into his 10 , and he smiled at me, I watched for a while．As 11 as it sounds, I expected something more to come from that moment -- a feeling of 12 or satisfaction, for example．But nothing happened 13 , I walked off．“It proved to be a waste of 14 ,”I thought．
On my way home at the end of the 15 , I saw the busker again and he was 16 ．I watched him pick up the hat and walk 17 a cafe counter．There he poured the 18 contents into a tin collecting 19 an earthquake fund-raising（募捐）event．He was busking for charity（慈善）！
Now I donate any 20 I have to charity tins and enjoy the feeling of giving．
