     I was working as a consultant in a beer company, helping the president and senior vice-presidents form

and carry out their new planning projects. It was really a great challenge.

     At the same time, my mother was in the final stages of cancer.

     I worked during the day and drove 40 miles home to be with her every night. It was tiring and stressful,

but it was what I wanted to do. My commitment was to continue to do excellent consulting during the day,

even though my evenings were very hard. I didn't want to bother the president with my situation, yet I felt

someone at the company needed to know what was going on. So I told the vice-president of Human

Resources, asking him not to share the information with anyone.

     A few days later, the president called me into his office.

     I figured he wanted to talk to me about one of the many issues we were working on. When I entered, he

asked me to sit down. He faced me from across his large desk, looked me in the eye and said, "I hear your

mother is very ill."

     I was totally caught by surprise and burst into tears. He just looked at me, let my crying subside (平息),

and then gently said a sentence I will never forget: Whatever you need.

     That was it. His understanding and his willingness both to let me be in my pain and to offer me everything

were qualities of sympathy that I carry with me to this day.
