As a general rule never leave a tied-up person alone...

A judge sentenced a Columbia woman to 18 months in jail in the death of her husband during a sex game. Rebecca Bargy, who is 26, was sentenced Monday in the death of her 29-year-old husband James Bargy in April 2008, according to The Daily Herald of Columbia.

Rebecca Bargy was convicted May 20 of negligent homicide — a lesser charge than the second-degree murder indictment against her. She was accused of tying up and gagging her husband as part of a bondage fantasy and leaving him alone in their mobile home for 20 hours while she was with another man she had met on the Internet.

...but if you must—and some must—never leave 'em alone gagged and never for 20 freakin' hours.
