Paul tripped and fell, injuring his left knee and experiencing pain and swelling. A friend helped him home, where his mother, Madame Dubois, grew concerned about his condition despite Paul having taken an analgesic. Deciding he needed medical attention, Madame Dubois, accompanied by Marco, took Paul to a doctor's office without an appointment. The doctor examined Paul and sent him for an X-ray to confirm the injury, which revealed no fracture but a sprain. Paul was prescribed antibiotics, paracetamol, and vitamin D syrup, along with instructions for seven days of bed rest and a follow-up if his condition didn't improve. Madame Dubois paid for the consultation, and they then went to a pharmacy to purchase the prescribed medications.
