The author is a member of a peace organization, and he went to Cuba with others to attend a peace conference.
After returning to the country, he received a letter from a U.S. bank saying that because he had been to Cuba, the bank would close the accounts of him and his family.
The author found it very strange because attending a peace conference in Cuba was legal, and he had done nothing wrong.
The author said that peace conferences are very important, as people can discuss together how to make the world more peaceful.
He also said that the bank's action made him very sad, but he would not give up working for peace because of this.
He hopes everyone can face difficulties bravely, and also hopes the bank will treat everyone more fairly.
