Good morning Teacher,
I am Shajahan F, father of Milan S of your class 8th B. I am messaging from my personal cell phone number. I am leaving this message to let you know that my son will be absent today. He has a fever and is sick since last night. I will be taking him to the hospital today.
I kindly request that you grant him a leave today so that he can visit the hospital and take some rest. He will resume attending the class once he is fine and healthy. I will ensure that he goes through all the lessons that will be taught on the days of his absence and completes the notes.
