July 26, 2002 Dear Wang Wei, I am terribly sorry to tell you that I have lost the valuable book Who Moved My Cheese You were so kind to lend it to me last week. I read it every evening and finished it last night. I intended to return it today, but when I came to my bedroom, it was no where to be found. I tried to find it everywhere, but I failed to, so I will get a new copy for you. But I am afraid it can never take the place of the old one. Old books are like old friends. Once lost, they can never be replaced. And for this irrecoverable (无法弥补的) loss, I am to blame. I was so careless with my things, This is a warning to me to be more careful in future. Please accept my sincere apologies. Yours, Wei Hua What would the author do when he could not find the old book Get a new copy to replace ______.
