Dear Mrs. C--
Thank you for the extension, I have my essay but I want to hand it straight to you because I've had the experience of having an assignment gone missing when just placed on a teacher's desk or handed to a sub. I've been through that many times before and I'm just a little paranoid about it. I'm also gonna send you an email saying pretty much the same thing in case the note gets lost or technology fails. Also, I really appreciate the way you teach because you honestly care and try to have a relationship with your hundreds of students and you treat us like people and you don't throw work in our faces and expect us to know what to do, you explain things and take time to make sure everyone understands and has the tools/resources they need. You are by far one of the Best Teachers ever.
Sincerely,
Mitzi
