[header] How to get a sick note [title] Ask your parents to write a note. [step] Many schools don't require a doctor's note for sickness, and many doctors will not write formal notes for school absences. Your parent or guardian can write a sick note for your teacher after you recover or drop it off personally. 
[substeps] Be sure that the note written by your parent or guardian has the date of your illness. It should also address the teacher and have a brief explanation of why you are absent.
