‘Yep.’ Louise plopped her hand on her big brother’s knee. ‘We are together. That’s why we’re both here, right? To look after each other.’ John sighed at her obvious mocking of the situation, but was just relieved that she had decided not to embarrass him even further.

The doctor, showing no sign of suspicion, nodded and smiled. ‘Great. You’re a very supportive partner,’ she said, bowing slightly to Louise, who loved every second of the incorrect title. There was no way John would ever hear the end of this once they left. ‘Alright. Can I ask you, John, to take off your pants, so I can get a better look at what I’m dealing with here.’ He stood as the doctor grabbed a pair of latex gloves and pulled them on. ‘Can you tell me where exactly this weird pain is coming from, in that area?'
