First on my dead list is the couple who were originally DH's friends. After a mere 15 years they still don't know how to spell my name (they've got 15 Christmas cards from me to refer to and it's not that hard) and they address cards to Mr Hassled alone. They're going the fuckers.
Also going is the ex-colleague who was never really very nice to me at all. This is less clear cut because she does always include a tenner for the kids in her card. But she was/is a bit of a cow and I don't have any other contact and I'm in ruthless mode.
