In a used furniture business, unlike new, you cannot order stock from a catalogue. People call in, and you have to go out and make an offer. “You can't ______ what you don't have，” my father would say.

When I was aged thirteen, my father ______ his store manager, a one－armed guy who could do more with his one arm than many will do with two. With his ______ gone, my father came to me. “Will you come in while I go out to ______ the day's calls ______ I find the right person？” he asked. The store has tens of thousands of ______. “People like to bargain，” he told me. “So I don't ______ prices. You just have to know a ______．”

He took me around and said, “A quarter－horse motor you can sell for four dollars. For a refrigerator, depending on the______，you can sell for thirty－five dollars to sixty dollars. However, if it has a freezer all the way across, sell it for eighty dollars; ______ excellent condition, maybe one hundred dollars. Dishes come in with a houseful of furniture, and I don't even figure them in when I give a price. You can sell them for a nickel to a quarter. Something really nice.”

Every day after ______，I would pedal(骑自行车) down to the store. Soon after, I was writing up a sales slip(纸条) for an attractive plate when my father walked in. I had asked a dollar and the guy did not hesitate. I was very ______. My father glanced down at what I was doing, ______ the customer and said, “You sure got a______ today. My employee gave you the price and that's the price.” Afterward, I asked my father, “What was that all______？”

It turned out that it was a(n) ______ plate, worth a few hundred dollars. I was shocked. Here I was ______ to help my father in the business and instead I was losing money for him.

He said, “I could have stopped the sales if I'd wanted to. You were just writing up the slip and hadn't yet taken the money. ______， by civil law, you're ______ age. But，a man stands by his word and the word of his agent.” It ______ my father a small amount of money, but I learned a lifelong lesson in integrity(正直)．
