Dear Ms Amber,
RE: Unable to Attend School
I wish to inform you that I, Ashley Asphodel of Year 5K is sick. I have chickenpox and flu. Therefore, I am unable to attend school for 20 days, starting from today.
My mother took me to see a doctor this morning. The doctor gave me some medicines and told me to rest at home. I will bring you the medicine certificate when I return to school.
I will return to school as soon as I have recovered.
