'One day' from a lady in Portugal

One day, Youngsters will learn words they will not understand,  Children from India will ask: "What is hunger?" Children from Alabama will ask: "What is racial segregation?" Children from Hiroshima will ask: "What is the atomic bomb?" Children at school will ask: "What is war?" You will answer them, you will tell them: "Those are words not used any more, Like 'stage-coaches', 'galleys' or 'slavery', Words no longer meaningful, That is why they have been removed from dictionaries."  Martin Luther King
