Calling in sick
When you’re a student you have to spin a lot of different plates. You have lectures and a job, housework (you know, when you occasionally change your sheets or empty the trash can), a personal life, and then all the adult stuff that you’re new at. Shopping, appointments, and calling writing your own sick notes.
This can be a problem when you really are too sick to actually write, or spell, or remember who you’re writing the note to. I agree with yay855: I would completely believe this was a genuine sick note if I received this email. I would also laugh at it a lot.
