People always refer to their husband's hobby, (usually he's off most of Saturday leaving the OP to care for 4 kids and the dog and coordinate a children's party) but never say what it is. This is usually because the hobby will be "outing". Unless it's swimming the coast of the UK dressed as Mr Blobby, the hobby will never be outing and the whole thread is derailed as people guess the hobby and OP argues relentlessly that it's not relevant. Can there be a ban on non specific hobbies ?
