Dear Dr.Johnson
I am sorry to inform you that I will be absent next Monday to Wednesday. I have a family emergency and will have to go out of town during those three days. My father is very sick and the doctor doesn't expect him to live very long. I'm going to request for an approval for my leave from the principal As soon as that is done, I'll make an appointment to get my work and other reading from you. If you want more information. You can call my parents 0931202001 or reply this email.
