What do you do when you really screw up?

Occasionally, however, I really blow it. Not burned oatmeal, nor burnt down house. More like burned sleeve of your favorite jacket? No, worse. More like, "I said something profoundly mean to someone whom I love more than sunshine," or "I just got a call from a potentially important prospect who was wondering where I am because I put our first meeting on the calendar for next week instead of RIGHTF**KINGNOW."
