We have thrown this birthday party not only to celebrate your fourty-fifth birthday,Bob,but,more importantly,to express our gratitude for your thoughtful leadership.We all want to say "thank you" to you.

　　It is really wonderful for all of us to grow older together and work together under Bob's leadership.And I'm sure Bob will also take the leadership in "staying young".

　　Happy birthday,Bob,and many more happy returns!
