I am a student in grade [grade number] at [school name] school. I am writing to inform you that I have become sick and have been vomiting since the early morning. This is why I was unable to attend school today. Please allow me to be absent 2 days (today and tomorrow).
May be its just me but i think the simplest is the best: tell 'em that u know u screwed up but u are asking 4 a 2nd chance and u will be responsible now.
