Stupid fucking cow-orker

The wife is on sick leave from work, due to being stressed out and overworked. She's not reading mail, her work mobile phone is turned off -- and a stupid fucking creep of a cow-orker hunts down our home phone number and calls at 9pm trying to get her to work. So now the home phone is disconnected, and I'm not even going to tell people which city she's in, in case some cretin decides to hunt her down physically and demand that she fix things.
