我也有同样的经历.在逛街的时候看到一个小流氓把一个大妈讨了一天的钱给强了. 大妈就哭着跟我往同一方向走.然后一个电话亭的女的把她叫住要换零钱.她好像每天都跟这个大妈换,大妈边哭边讲了what happended, and asked for some money for her dinner. of cuz the girl didn't give any......at this moment, i have exactly the same feeling you mentioned. nearly cried out. but one friend told me that, you can give her money. 100 also can. but you can't change her life for her......maybe he just wanna make me feel better or maybe he just said out the truth.
