I wandered into the small store where I usually buy milk, when the store owner received a call from a customer. The customer and his wife had shopped there several months earlier. He noticed that his wife really liked one thing in the store, so he wanted to buy it as a surprise.

    But the customer was in Tennessee, far away from the store which was in Maine. What was more, he had been to the store several months earlier, and it was difficult to believe that the store owner would remember him, or what he was looking for.

    The store owner took a few close-up photos with her camera, and e-mailed them to the customer on the computer. The customer looked at the photos, and decided which one he wanted. They talked and discussed a price over the phone. She took care of the credit card transaction (交易) online, and promised the gift would be shipped out that afternoon.

    The store owner was really smart. She was willing to push herself to find new ways to make the transaction actually happen. And it did work. However, it was the first time she had ever done it.

    I was amazed that the store owner discovered a creative solution that could lead to a new way of doing business. I was impressed by what she did—so easily, but how difficult it is for many of us to make that leap(飞跃). I'm not just talking about technology, but about learning how to adapt to change. Most people hate or fear change unless they get to know exactly what change needs to be made. However, we should realize that challenge and opportunity go hand in hand.

    Papa, as a son of a dirt-poor farmer, left school early and went to work in a factory, for education was for the rich then. So, the world became his school. With great interest, he read everything he could lay his hands on, listened to the town elders and learned about the world beyond his tiny hometown. "There's so much to learn," he'd say. "Though we're born stupid, only the stupid remain that way. "He was determined that none of his children would be denied (拒绝) an education.

    Thus, Papa insisted that we learn at least one new thing each day. Though, as children, we thought this was crazy, it would never have occurred to us to deny Papa a request. And dinner time seemed perfect for sharing what we had learned. We would talk about the news of the day; no matter how insignificant, it was never taken lightly. Papa would listen carefully and was ready with some comment, always to the point.

    Then came the moment—the time to share the day's new learning.

    Papa, at the head of the table, would push back his chair and pour a glass of red wine, ready to listen.

    "Felice," he'd say, "tell me what you learned today."

    "I learned that the population of Nepal is ...."

    Silence.

    Papa was thinking about what was said, as if the salvation of the world would depend upon it. "The population of Nepal. Hmm. Well……" he'd say. "Get the map; let's see where Nepal is." And the whole family went on a search for Nepal.

    This same experience was repeated until each family member had a turn. Dinner ended only after we had a clear understanding of at least half a dozen such facts.

    As children, we thought very little about these educational wonders. Our family, however, was growing together, sharing experiences and participating in one another's education. And by looking at us, listening to us, respecting our input, affirming our value, giving us a sense of dignity, Papa was unquestionably our most influential teacher.

    Later during my training as a future teacher I studied with some of the most famous educators. They were imparting what Papa had known all along—the value of continual learning. His technique has served me well all my life. Not a single day has been wasted, though I can never tell when knowing the population of Nepal might prove useful.
