You've written an email that says some things you might be better off saying in person—or not at all—right? Like when you wanted to tell off a co-worker—or supervisor—about taking credit for your work, or putting you down in front of the boss, or just for generally being a jerk. Maybe you were caught up in the anger of the moment—you let your temper get the best of you—or maybe you were just a bit—or a lot—drunk. And maybe you hit that "Send" button, and maybe you reconsidered before it was too late. I don't like to imagine the result of sending such a message.
