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 soft 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. 1 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.
The receiver of this letter is ______.
