    From: George Chen, Accounting Department
                             
    Date: March 11, 201x
                            
    Subject: Casual Leave of Absence
                             
    John, I would like to know if I could ask for a  casual leave of absence from March 23 to 27.
                            
    Yesterday I received a letter from my parents, who are both over 70, telling me that a big flood took  place at my home village, causing serious damage  to my house. As the only son of my parents, I should of back to assess the situation, and help  them to get over these difficulties. Though I cannot stay at home for too long a time, I should  at least make arrangements for repair work. I  believe my relatives in the village and my neighbors will also come to help. Financially I  have no difficulties.

     I will call you at 1:30p.m. or you can call me at  any time.
