Martha: I'm training to be a doctor. Not an alien doctor, a proper doctor, a doctor of medicine.
Joan: Well, that certainly is nonsense. Women might train to be doctors, but hardly a skivvy and hardly one of your colour.
Martha: Oh, d'you think? (holds up hand) Bones of the hand. Carpal bones, proximal row: scaphoid, lunate, triquetral, pisiform. Distal row: trapezium, trapezoid, capitate, hamate. Then the metacarpal bones, extending in three distinct phalanges: proximal, middle, distal.
Joan: You read that in a book.
Martha: Yes, to pass my exams!
