Dear Ms. Roberts,
I hope this email finds you well. My name is Ananya Patel, and I am a student in Class 10B. I am writing to request a leave of absence due to illness.
I have been advised by my doctor to rest for three days. Therefore, I will not be able to attend school from October 20th to October 22nd. I have attached a copy of my medical certificate for your reference.
Thank you for your understanding.
Sincerely,
Ananya Patel
Class 10B
