Nicholas Winton was a young stockbroker who was 28 years old from London. He saved so many children from a death threat in Czechoslovakia. After World War Ⅱ, one day, his wife found a scrapbook. This scrapbook had the children's photographs, telegrams, and letters from their parents. Surprisingly, he never told his wife, "I do". While watching the films, I thought, "What should I teach to children now?" How horrifying people can be when angry. People can be cruel. In my opinion, we should teach humanity about people like, Irena Sendler, Oskar Schindler, Chiune Sugiura, Sophia Scholl, Leopold Sochafrom and Nicholas Winton.
