英文原版

“The man of my dreams has almost faded now. The one I have created in my mind. The sort of man each woman dreams of in the deepest and most secret reaches of her heart. I can almost see him now before me. What would I say to him, if he were really here? Forgive me, I've never known this feeling. I've lived without it all my life. Is it any wonder then I failed to recognize you? You -- who brought it to me for the first time. Is there any way that -- that I can tell you how my life has changed? Any way at all to let you know what sweetness you've given me? There is so much to say. . . I cannot find the words. Except for these -- I love you! ”

台词汉译

“我遇见了我梦中的情人。他是我一直朝思暮想的人。他是那种每个女子都会梦到的、存在于心中最深最隐秘处的情人。我在现在几乎可以看到他在眼前，如果他真的在这里，我会对他说什么？请原谅我，我从来不懂这种感觉。我一生都不曾有过这种感觉。也难怪我没有认出你来。是你，第一次给我带来这种感觉。有没有任何方法可以让我告诉你，我的生命如何发生了改变？到底有没有任何方式可以让你知道你给我带来的甜蜜？我有好多话要说···却找不到适当的话语。但除了这个——我爱你！
