I know a Thai that broke his wife's arm by twisting up behind her back until it snapped. Both bones in the forearm - compound fractures that came through the skin. He was stone cold sober (didn't drink). No apparant reason for such a violent action, she asked him about his trip to Udon and a certain girl who had texted her (he had borrowed her mobile) with suspicious messages ('i miss you' etc). He had been caught out and, I gess lost face, so snapped.

This was several years ago now (both worked together running a business that was sucessful back then) so no money worries or real pressure. The have been divorced for about five years again and both have new partners. She still says she fell over - I guessed straight off and both of them admitted it to me. She was ashamed and he felt very guilty about it.

Snap!
