Pierre and I borrowed the money and bought the necklace. During the next ten years we both worked day and night to pay back the money we had borrowed. That's why I now look so old. Well, after all these years we've at last paid back all the money.

我和比尔借了一笔钱，买下了那条项链。在后来的10年时间里，我们两人为了偿还这笔借款不分昼夜地干活。这就是为什么我现在看起来这样老的原因。好了，过了这些年之后，我们终于还清了全部借款。
