In London, there are certain women who ring the hospital maternity department, to ask what they should do, as they are having contractions 1 hour apart, who then suffer from a little know medical condition: Maternity Deafness. This condition manifests itself by the patient not hearing certain words. The midwife/sister/staff nurse says "Come to the hospital as soon as you can, but dont call an ambulance." But the patient only hears: "Come to the hospital as soon as you can, call an ambulance."
