英语请假条的例子　　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.
