An awake politician has made it a habit to make excuses by blaming other countries whenever something bad happens in his own country. He never repeats the country he targeted in his previous excuse. Whenever journalists ask for comments, the adviser writes on paper the name of a country other than the one used in the previous pretext and holds it in his hand. Write an excuse to facilitate the consultant's job, in accordance with the following main function named Summer.
