l am terribly sorry to tell you that l have lost the valuable book you were so kind to lend me last week.The book was missing because of my carelessness.Yesterday l took the book with me to the park and read it there.But when l came back home ,it was nowhere to be found.l tried to look for it everywhere but in vain.So l bought a new one for you.
l know books are like friends.Once lost,they can never be replaced.l am afraid zhe new book can never take the place of the old one .And about this irrecoverable loss,l feel really guilty.l have always been careless with my things.this is a warning to me to be more careful in the future.
