1. Don't send me an email that says, "Thank you." Or "thanks," or, and this is the worse, "thx."
2. Put something in the subject line, or I will delete your message without reading it. I will also think you are dumber than a fifth-grader.
3. Do not ever, ever, ever forward me a PowerPoint presentation that includes blurry pictures of roses or kittens and instruct me to send it to those I love.
