I told him 1 that the main reason why I was 2 with them was my 3 to keep my family in Boston. My wife of 26 years old had recently died of a heart attack. A(n) 4 in Boston would also help me reduce some of the pain of the loss. Bruce, the interviewer, was politely sympathetic, and didn't probe (调查) any 5 .He acknowledged my loss and, with great respect, moved on to another 6 . After the next 7 of interview, Bruce took me to lunch with another manager. Then he asked me to take a 8 with him. He told me that he, 9 , had lost his wife. And he had also been married 20 years and had three children. In his sharing, I realized that he had 10 the same pain as I had, a pain that was almost 11 to explain to someone who had not lost a loved 12. He offered his business card and home phone number and 13 that, if I needed help or just wanted someone to 14 , I should feel 15 to give him a call, no matter 16 I got the job or not. He wanted me to know that he was there if I 17 needed any help. From that one act of kindness, when he had no 18 whether we would ever see each other again, he helped me 19 one of life's greatest losses. He turned the normal 20 business interview process into an act of caring and support for another person in a time of need. | ||||
