I think this man would have been better off trying to mediate this dispute rather than the extreme tact he took.

Vienna, October 26, 2006

A Viennese man cut off his ring finger and presented the digit, still holding his wedding band, to his ex-wife after an acrimonious divorce, Austrian news agency APA reported.

Charged with dangerous harassment and assault for the act, he told a preliminary hearing he did not regret having cut off the finger and had chosen deliberately not to reattach it.

“It was an act of breaking free,” the man was quoted as saying. He did not miss his finger, could work well without it and did not plan on getting married again anyway, he said.
