| I was being interviewed by a senior manager for a major insurance (保险业) company. I told him honestly why I wanted the job-I needed to keep my family in Boston. My wife recently died of a heart attack (心脏病). A job in Boston would help me reduce some of the extreme trauma (精神创伤) and pain of the loss for my 16-year-old daughter. It was important for me to keep her in her high school. I could still hardly talk about the loss of my wife. Bruce, the interviewer, was politely empathetic, but he didn't probe (彻底调查) any further. He admitted (接受) my loss and, with great respect, moved on to another subject. After the next round of the interview, Bruce took me to lunch with another person. Then he asked me to take a walk with him. He told me that he, too, had lost his wife. And, like me, he had also been married 20 years and had three children. In his sharing, I realized that he had experienced the same pain as I had a pain that was almost impossible to explain to someone who had not lost a beloved one. He offered his business card and home phone number and suggested that, if I need help or just want someone to talk to, I should feel free to give him a call. Whether I got the job or not, he wanted me to know that he was there if I ever needed help. When he had no idea if we would ever see each other again, he helped our family deal with one of the greatest losses. He turned the normally cold business interview into a caring support for another person in need. |
