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 recieved 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 go 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 1:30 p. m. or you can call me at any time.

George
