how i solidified one student's hatred with a click of the mouse

The Letter (written in much kinder language, but with the same general message):

Dear Mrs. Joseph's Mom,

I am writing to inform you that your son is obnoxious. His grades suck, and he's lazy. Thanks for listening!

Love,
Ms. Reed

And then it was sent. And then I realized it's Joseph's birthday. So now I suck.
