I'm very grateful for what you have done to my son , doctor .   That's all tight , Mr.Smith.That ' s my job . I'm very glad he recovered so soon .   I know he has brought great trouble to you . A million thanks .   No trouble at all . He's very cute and brave . By the way , do remember to keep him away from sea food for at least two weeks .   I will . It's most thoughtful of you .
