I come from a close, loving family. I have three elder brothers.

My parents owned a wood supply business.  71  When I was a kid, people used to laugh at my dad and say his volunteer work was his business and his business was his hobby .That rubbed off on me. For example, I was a Big Brother in high school, and I continued doing volunteer work in college.

In 1979, just before graduation, my brother Mark asked if I’d like to help him start a software company.  72  And I was happy that later it became very unusual in the software industry. Once I started working, I continued to volunteer.

  73  So I volunteer to company the elderly persons who live alone. I met Malcolm, who’s physically healthy.  74  He is also interested in my work. He often says “You can get caught up being the CEO of a half-billion-dollar software company very quickly.”

I learn kindness, humility(谦恭), a positive outlook on life from Malcolm.  75  But we have been together for five years and there is no end in sight.

A. So I joined his company.    

B. They are successful in the business.

C. Most people volunteer for a year.   

D. But they were active volunteers in our community.

E. He learn how to do volunteer work from me .

F. I’m a big believer that you learn from those around you by volunteering.

G. We talk about what friends talk about.
