I shook hands with my father in the truck, and for a long time he looked straight ahead and didn’t say a word. But I knew he was going to say a little to me. “I can’t tell     ,” he finally said. “I never went to college, andnone of your      went to college. I can’t say don’t do this and do that,      everything is different. And I don’t know      is going to come up. I can’t help much with money,     , but I think things will work out. ”

He gave me a new check-book(支票簿). “If you are short of money,      a small check. But when you write one, send me a letter and let me     how much. There are some things we can always sell.” In four years all the checks I wrote were less than a thousand dollars. My part-time jobs such as      to the blind student and sitting with the teachers’ kids filled in the financial gaps.

“You know what you want to be, and they’ll tell you what to take,” my father went on. “When you get a job, be sure it’s honest, and work hard.”

Then my dad reached down beside his seat and brought the old,      Bible that he had read so often. He didn’t say read this every morning. He just said, “This can help you if you will let it.”

Did it help? I got through college      being a burden on the family. I have been able to make money since.
