Hello, Professor OOO!
I was in the OOO section.
My name is OOO, OOO department, OOO university.
First, send me an email while you are busy.
I am writing this email to ask you about my grades.
I was trying to figure out what was missing, but if you don't mind, what was missing wasn't.
I need you to tell me what it is.
I will be waiting for your reply. The weather is cold these days, so be careful for the flu. Thank you.
