That's the difference

这就是区别所在

A teenager lost a contact lens while playing basketball in his driveway.

After a fruitless search, he told his mother the lens was nowhere to be found. Undaunted, she went outside and in a few minutes, returned with the lens in her hand. "How did you manage to find it, Mom?" the teenager asked. "We weren't looking for the same thing," she replied. "You were looking for a small piece of plastic. I was looking for $150."

孩子在车库打球时掉了一只隐形眼镜。

找了一会儿，他告诉母亲找不到了。母亲出去了，几分钟以后，拿着隐形眼镜回来。“妈妈，你是怎么找到的?”孩子问。“我们找的不是同一件东西，”母亲回答，“你找的是一小片塑料，而我是在找150块钱。”
