Same thing happened to me late last year, she was really upset and I did feel sorry for her, not my problem really though,
Still don't know which client it was, if I ever find out he will get a bollocking off me for being careless with my details!
This wife threatened to call the police on me but I'm not doing anything illegal so wasn't too worried, would be more worried about her telling the neighbours but don't think she knew where I was, just my name and number.
