Return Reciept

I have an irrational hatred for "return receipts" on email. You know those "special" people who send you email that forces a pop-up that says the sender wants to be notified when I read the message. I think it's just plain rude. I will read the message when I feel like it and I will definitely not let you know when that is. I have never once, in my life, clicked OK. I suggest you don't either.
