**Introduction**

Doctor Sadao, the protagonist of the short story "Flamingo" by K.M. Peyton, is forced to become impatient and irritable with his patient due to several reasons. This paper will explore these reasons in detail and provide a comprehensive analysis of the situation.

**1. Lack of Cooperation**

One of the primary reasons for Doctor Sadao's impatience and irritability is his patient's lack of cooperation. The patient, an American prisoner of war, is suffering from a critical wound and requires immediate medical attention. However, he refuses to provide any information about himself or his identity, making it difficult for Doctor Sadao to properly diagnose and treat him.

**2. Limited Resources**

Doctor Sadao is also facing the challenge of limited resources. The story is set in Japan during World War II, and the country is experiencing scarcity of medical supplies and equipment. Doctor Sadao is unable to provide the best possible care for his patient due to the constraints imposed by the war. This limitation adds to his frustration and contributes to his impatience.

**3. Ethical Dilemma**

Another factor that contributes to Doctor Sadao's impatience is the ethical dilemma he faces. As a Japanese citizen, he is torn between his duty to his country and his duty as a doctor to save lives. The patient is an enemy soldier, and treating him goes against the nationalistic sentiment prevalent at the time. This internal conflict causes Doctor Sadao to feel a sense of resentment towards his patient, leading to impatience and irritability.

**4. Emotional Burden**

Doctor Sadao is burdened with a heavy emotional weight throughout the story. He is torn between his loyalty to his country and his duty to humanity. This emotional burden exacerbates his impatience with the patient, as he struggles to reconcile his personal feelings with his professional obligations. The stress and pressure he experiences result in impatience and irritability.

**Conclusion**

In conclusion, Doctor Sadao's impatience and irritability with his patient in "Flamingo" are primarily influenced by the patient's lack of cooperation, limited resources, ethical dilemma, and emotional burden. These factors, combined with the challenging circumstances of wartime Japan, contribute to Doctor Sadao's frustration and impatience. It is important to note that despite his impatience, Doctor Sadao ultimately chooses to prioritize his duty as a doctor and saves the patient's life.
