Gmail: Saving Me From Myself

I just wrote an e-mail to a new client and mentioned I was attaching something.  When I hit "send," a dialog popped up:

"You wrote 'Attached is' in your message, but no files are attached.  Send anyway?"

Translation: "Hey, moron, try to get with the program!  Do you want this guy's business or not?!"

Gmail, I love you.  More than is probably healthy.
