john, i would like to know if i could ask for a casual leave of absencefrom 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 seriousdamage to my house. as the only son of my parents, i should of back to assessthe situation, and help them to get over these difficulties. though i cannotstay at home for too long a time, i should at least make arrangements for repairwork. i believe my relatives in the village and my neighbors will also come tohelp. financially i have no difficulties.
i will call you at 1:30p.m. or you can call me at any time.
