一个小小的错误,有可能幸运地导致一个意外的发现。儿子走上前来,向我报告幼儿园里的新闻,说他又学会了新东西,想在我面前显示显示。他打开抽屉,拿出一把还不该他用的小刀,又从冰箱里取出一个苹果,说:“爸爸,我要让您看看里头藏着什么。” A small mistake may be fortunate enough to lead to an unexpected discovery. The son came up and told me about the news in the kindergarten. He said that he had learned something new and wanted to display it in front of me. He opened the drawer and took out a knife that he shouldn’t have used. He took an apple out of the fridge and said, “Dad, I want you to see what’s hidden inside.”
